+
+Version 7.15.1 (7 December 2005)
+
+Daniel (6 December 2005)
+- Full text here: http://curl.haxx.se/docs/adv_20051207.html Pointed out by
+  Stefan Esser.
+
+  VULNERABILITY
+
+  libcurl's URL parser function can overflow a malloced buffer in two ways, if
+  given a too long URL.
+
+  These overflows happen if you
+ 
+  1 - pass in a URL with no protocol (like "http://") prefix, using no slash
+      and the string is 256 bytes or longer. This leads to a single zero byte
+      overflow of the malloced buffer.
+
+  2 - pass in a URL with only a question mark as separator (no slash) between
+      the host and the query part of the URL. This leads to a single zero byte
+      overflow of the malloced buffer.
+
+  Both overflows can be made with the same input string, leading to two single
+  zero byte overwrites.
+
+  The affected flaw cannot be triggered by a redirect, but the long URL must
+  be passed in "directly" to libcurl. It makes this a "local" problem. Of
+  course, lots of programs may still pass in user-provided URLs to libcurl
+  without doing much syntax checking of their own, allowing a user to exploit
+  this vulnerability.
+
+  There is no known exploit at the time of this writing.
+
+
+Daniel (2 December 2005)
+- Jamie Newton pointed out that libcurl's file:// code would close() a zero
+  file descriptor if given a non-existing file.
+
+Daniel (24 November 2005)
+- Doug Kaufman provided a set of patches to make curl build fine on DJGPP
+  again using configure.
+
+- Yang Tse provided a whole series of patches to clear up compiler warnings on
+  MSVC 6.
+
+Daniel (17 November 2005)
+- I extended a patch from David Shaw to make libcurl _always_ provide an error
+  string in the given error buffer to address the flaw mention on 21 sep 2005.
+
+Daniel (16 November 2005)
+- Applied Albert Chin's patch that makes the libcurl.pc pkgconfig file get
+  installed on 'make install' time.
+
+Daniel (14 November 2005)
+- Quagmire reported that he needed to raise a NTLM buffer for SSPI to work
+  properly for a case, and so we did. We raised it even for non-SSPI builds
+  but it should not do any harm. http://curl.haxx.se/bug/view.cgi?id=1356715
+
+- Jan Kunder's debian bug report
+  http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=338680 identified a weird
+  error message for when you try to upload a file and the requested directory
+  doesn't exist on the target server.
+
+- Yang Tse fixed compiler warnings in lib/ssluse.c with OpenSSL 0.9.8 and in
+  lib/memdebug.h that showed up in his msvc builds.
+
+Daniel (13 November 2005)
+- Debian bug report 338681 by Jan Kunder: make curl better detect and report
+  bad limit-rate units:
+  http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=338681 Now curl will return
+  error if a bad unit is used.
+
+- Thanks to this nice summary of poll() implementations:
+  http://www.greenend.org.uk/rjk/2001/06/poll.html and further tests by Eugene
+  Kotlyarov, we now know that cygwin's poll returns only POLLHUP on remote
+  connectin closure so we check for that case (too) and re-enable poll for
+  cygwin builds.
+
+Daniel (12 November 2005)
+- Eugene Kotlyarov found out that cygwin's poll() function isn't doing things
+  right: http://curl.haxx.se/mail/archive-2005-11/0045.html so we now disable
+  poll() and use select() on cygwin too (we already do the same choice on Mac
+  OS X)
+
+- Dima Barsky patched problem #1348930: the GnuTLS code completely ignored
+  client certificates! (http://curl.haxx.se/bug/view.cgi?id=1348930).
+
+Daniel (10 November 2005)
+- David Lang fixed IPv6 support for TFTP!
+
+- Introducing range stepping to the curl globbing support. Now you can specify
+  step counter by adding :[num] within the brackets when specifying a range:
+
+   [1-100:10]
+   [a-z:2]
+
+  If no step counter is set, it defaults to 1 as before:
+
+   [1-100]
+   [d-h]
+
+Daniel (8 November 2005)
+- Removed the use of AI_CANONNAME in the IPv6-enabled resolver functions since
+  we really have no use for reverse lookups of the address.
+
+  I truly hope these are the last reverse lookups we had lingering in the
+  code!
+
+- Dmitry Bartsevich discovered some issues in compatibilty of SSPI-enabled
+  version of libcurl with different Windows versions. Current version of
+  libcurl imports SSPI functions from secur32.dll. However, under Windows NT
+  4.0 these functions are located in security.dll, under Windows 9x - in
+  secur32.dll and Windows 2000 and XP contains both these DLLs (security.dll
+  just forwards calls to secur32.dll).
+
+  Dmitry's patch loads proper library dynamically depending on Windows
+  version. Function InitSecurityInterface() is used to obtain pointers to all
+  of SSPI function in one structure.
+
+Daniel (31 October 2005)
+- Vilmos Nebehaj improved libcurl's LDAP abilities:
+
+  The LDAP code in libcurl can't handle LDAP servers of LDAPv3 nor binary
+  attributes in LDAP objects. So, I made a quick patch to address these
+  problems.
+
+  The solution is simple: if we connect to an LDAP server, first try LDAPv3
+  (which is the preferred protocol as of now) and then fall back to LDAPv2.
+  In case of binary attributes, we first convert them to base64, just like the
+  openldap client does. It uses ldap_get_values_len() instead of
+  ldap_get_values() to be able to retrieve binary attributes correctly. I
+  defined the necessary LDAP macros in lib/ldap.c to be able to compile
+  libcurl without the presence of libldap
+
+Daniel (27 October 2005)
+- Nis Jorgensen filed bug report #1338648
+  (http://curl.haxx.se/bug/view.cgi?id=1338648) which really is more of a
+  feature request, but anyway. It pointed out that --max-redirs did not allow
+  it to be set to 0, which then would return an error code on the first
+  Location: found. Based on Nis' patch, now libcurl supports CURLOPT_MAXREDIRS
+  set to 0, or -1 for infinity. Added test case 274 to verify.
+
+- tommink[at]post.pl reported in bug report #1337723
+  (http://curl.haxx.se/bug/view.cgi?id=1337723) that curl could not upload
+  binary data from stdin on Windows if the data contained control-Z (hex 1a)
+  since that is treated as end-of-file when read in text mode. Gisle Vanem
+  pointed out the fix, and I made both -T and --data-binary take advantage of
+  it.
+
+- Jaz Fresh pointed out that if you used "-r [number]" as was wrongly described
+  in the man page, curl would send an invalid HTTP Range: header. The correct
+  way would be to use "-r [number]-" or even "-r -[number]". Starting now,
+  curl will warn if this is discovered, and automatically append a dash to the
+  range before passing it to libcurl.
+
+Daniel (25 October 2005)
+- Amol Pattekar reported a bug with great detail and a fine example in bug
+  #1326306 (http://curl.haxx.se/bug/view.cgi?id=1326306). When using the multi
+  interface and connecting to a host with multiple IP addresses, and one of
+  the addresses fails to connect (the server must exist and respond, just not
+  accept connections) libcurl leaks a socket descriptor. Thanks to the fine
+  report, I could find and fix this.
+
+Daniel (22 October 2005)
+- Dima Barsky reported a problem with GnuTLS-enabled libcurl in bug report
+  #1334338 (http://curl.haxx.se/bug/view.cgi?id=1334338). When reading an SSL
+  stream from a server and the server requests a "rehandshake", the current
+  code simply returns this as an error. I have no good way to test this, but
+  I've added a crude attempt of dealing with this situation slightly better -
+  it makes a blocking handshake if this happens. Done like this because fixing
+  this the "proper" way (that would handshake asynchronously) will require
+  quite some work and I really need a good way to test this to do such a
+  change.
+
+Daniel (21 October 2005)
+- "Ofer" reported a problem when libcurl re-used a connection and failed to do
+  it, it could then accidentally actually crash. Presumably, this concerns FTP
+  connections.  http://curl.haxx.se/bug/view.cgi?id=1330310
+
+- Temprimus improved the MSVC makefile so that the static debug SSL libs are
+  linked to the executable and not to the libcurld.lib
+  http://curl.haxx.se/bug/view.cgi?id=1326676
+
+- Bradford Bruce made the windows resolver code properly return
+  CURLE_COULDNT_RESOLVE_PROXY and CURLE_COULDNT_RESOLVE_HOST on resolving
+  errors (as documented).
+
+Daniel (20 October 2005)
+- Dave Dribin made libcurl understand and handle cases when the server
+  (wrongly) sends *two* WWW-Authenticate headers for Digest. While this should
+  never happen in a sane world, libcurl previously got into an infinite loop
+  when this occurred. Dave added test 273 to verify this.
+
+- Temprimus improved the MSVC makefile: "makes a build option available so if
+  you set rtlibcfg=static for the make, then it would build with /MT. The
+  default behaviour is /MD (the original)."
+  http://curl.haxx.se/bug/view.cgi?id=1326665
+
+Daniel (14 October 2005)
+- Reverted the LIBCURL_VERSION_NUM change from October 6. As Dave Dribin
+  reported, the define is used by the configure script and is assumed to use
+  the 0xYYXXZZ format. This made "curl-config --vernum" fail in the 7.15.0
+  release version.
+
+Version 7.15.0 (13 October 2005)
+
+Daniel (12 October 2005)
+- Michael Sutton of iDEFENSE reported and I fixed a securitfy flaw in the NTLM
+  code that would overflow a buffer if given a too long user name or domain
+  name. This would happen if you enable NTLM authentication and either
+
+  A - pass in a user name and domain name to libcurl that together are longer
+      than 192 bytes
+
+  B - allow (lib)curl to follow HTTP "redirects" (Location: and the
+      appropriate HTTP 30x response code) and the new URL contains a URL with
+      a user name and domain name that together are longer than 192 bytes
+
+  See http://curl.haxx.se/docs/security.html for further details and updates
+
+Daniel (5 October 2005)
+- Darryl House reported a problem with using -z to download files from FTP.
+  It turned out that if the given time stamp was exact the same as the remote
+  time stamp, the file would still wrongly be downloaded. Added test case 272
+  to verify.
+
+Daniel (4 October 2005)
+- Domenico Andreoli fixed a man page malformat and removed odd (0xa0) bytes
+  from the configure script.
+
+- Michael Wallner reported that the date parser had wrong offset stored for
+  the MEST and CEST time zones.
+
+Daniel (27 September 2005)
+- David Yan filed bug #1299181 (http://curl.haxx.se/bug/view.cgi?id=1299181)
+  that identified a silly problem with Content-Range: headers with the 'bytes'
+  keyword written in a different case than all lowercase! It would cause a
+  segfault!
+
+- TJ Saunders of the proftpd project identified and pointed out problems with
+  the modified FTPS negotiation change of August 19 2005. Thus, we revert the
+  change back to pre-7.14.1 status.
+
+Daniel (21 September 2005)
+- Fixed "cut off" sentence in the libcurl-tutorial man page:
+  http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=329305
+
+- Clarified in the curl_easy_setopt man page what the default
+  CURLOPT_WRITEFUNCTION and CURLOPT_WRITEDATA mean:
+  http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=329311
+
+- Clarified in the curl_easy_setopt man page that CURLOPT_ERRORBUFFER
+  sometimes doesn't fill in the buffer even though it is supposed to:
+  http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=329313
+
+- When CURLE_URL_MALFORMAT is returned due to a missing URL, it now has an
+  error string set.
+
+Daniel (19 September 2005)
+- Dmitry Bartsevich made the SSPI support work on Windows 9x as well.
+
+Daniel (15 September 2005)
+- Added a TFTP server to the test suite and made the test suite capable of
+  using it.
+
+Daniel (7 September 2005)
+- Ben Madsen's detailed reports that funnily enough only occurred with certain
+  glibc versions turned out to be curl using an already closed file handle
+  during certain conditions (like when saving FTP server "headers").
+
+- Scott Davis helped me track down a problem in the test HTTP server that made
+  test case 56 wrongly fail at times. It turned out it was due to the server
+  finding the end of a chunked-encoded POST too early.
+
+Daniel (6 September 2005)
+- Now curl warns if an unknown variable is used in the -w/--writeout argument.
+
+Daniel (4 September 2005)
+- I applied Nicolas Fran<61>ois' man page patch he posted to the Debian bug
+  tracker. It corrected two lines that started with apostrophes, which isn't
+  legal nroff format. http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=326511
+
+- Added --ftp-skip-pasv-ip to the command line tool, that sets the new
+  CURLOPT_FTP_SKIP_PASV_IP option. It makes libcurl re-use the control
+  connection's IP address when setting up the data connection instead of
+  extractting the IP address from the PASV response. It has turned out this
+  feature is frequently needed by people to circumvent silly servers and silly
+  firewalls, especially when FTPS is used and the PASV command-response is
+  sent encrtyped.
+
+  Sponsored by CU*Answers
+
+Daniel (1 September 2005)
+- John Kelly added TFTP support to libcurl. A bunch of new error codes was
+  added. TODO: add them to docs. add TFTP server to test suite. add TFTP to
+  list of protocols whereever those are mentioned.

+The main problem lies in two areas. First the bulk of support for libcurl
+exists for a Unix/linux command line environments. This is of little help when
+it comes to Windows O/S.
+
+Secondly the help that does exist for the Windows O/S focused around mingw
+thru a command line argument environment.
+
+You may ask "Why is this a problem?"
+
+I'm using a Windows O/S with DevCpp. For those of you who are unfamiliar with
+DevCpp, it is a window shell GUI that replaces the command line environment
+for gcc. A definite improvement that I am unwilling to give up. However using
+DevCpp presented its own set of issues. Inadvertently I also made some
+careless errors such as compiling the 7.14 version of Makefile with an older
+version of source code. Thanks to Dan Fandrich for picking this up.
+
+I did eventually with the help of Daniel, Phillipe and others manage to
+implement successfully (the only mingw available version)
+curl-7.13.0-win32-ssl-devel-mingw32 into the DevCpp environment. Only the
+dynamic libcurl.dll libcurldll.a libraries worked. The static library which I
+was interested in did not. Furthermore when I tried to implement one of the
+examples included with the curl package (get info.c) it caused the executable
+to crash. Tracing the bug I found it in the code and function res =
+curl_easy_perform(curl);.
+
+At this point I had to make a choice as to whether invest my limited
+time-energy resource to fixing the bug or to compile the new version
+available. After searching the archives I found a very similar or the same bug
+reported from version 7.12x on. Daniel did inform me that he thought that this
+bug had been fixed with the latest version. So I proceeded to compile the
+latest SSL version where I faced other challenges.
+
+In order to make this process unremarkable for others using the same
+environment I decided to document the process so that others will find it
+routine. It would be a shame if newbies could not implement this excellent
+package for their use.
+
+I would like to thank the many others in this forum and in the DevCpp forum
+for their help. Without your help I may either have given up or it would have
+taken me many times longer to achieve success.
+
+The Cookbook Approach
+---------------------
+
+This discussion will be confined to a SSL static library compilation and
+installation. Limited mention and comments will be inserted where appropriate
+to help with non-SSL, dynamic libraries and executables.
+
+
+   Using Makefile from DevCpp to compile Libcurl libraries
+
+Preamble
+--------
+
+Using the latest version release - curl-7.14.0.tar.gz. Curl source code is
+platform independent. This simply means that the source code can be compiled
+for any Operating System (Linux/Unix Windows etc. and variations of thereof).
+
+The first thing to note is that inside curl-7.14.0 you will find two folders
+lib and src. Both contain Makefile.m32 (required for win mingw library or exe
+compilation) files which are different. The main difference between these two
+folders and the makefiles is that the src folder contents are used to compile
+an executable file(curl.exe) while the lib folder contents are used to compile
+a static (libcurl.a) and dynamic (libcurl.dll & libcurldll.a) file that can be
+used to compile libcurl with your own source code so that one can use and
+access all libcurl functions.
+
+Before we start please make sure that DevCpp is installed properly. In
+particular make sure you have no spaces in the name of any of the directories
+and subdirectories where DevCpp is installed. Failure to comply with the
+install instructions may produce erratic behaviour in DevCpp. For further info
+check the following sites
+
+http://aditsu.freeunixhost.com/dev-cpp-faq.html
+http://sourceforge.net/forum/message.php?msg_id=3252213
+
+As I have mentioned before I will confine this to the SSL Library compilations
+but the process is very similar for compilation of the executable - curl.exe;
+just substitute the src folder makefile in its stead.
+
+First use a text processor Notepad, or your own favourite text processor. To
+engage your favourite text processor, select Makefile.m32 click once with your
+mouse on file icon; icon turns blue, press the shift key and right-click on
+mouse, menu appears select "Open with", select your favourite text processor.
+
+Next read the contents of Makefile.m32. It includes instructions on its use.
+
+Method I - DOS Command Line
+---------------------------
+ 
+Note - The only reason I have included this method is that Method II which is
+the preferred method for compiling does not allow for the setting of option
+switches (e.g. SSL = 1 or SSL =0). At least that's what they tell me at the
+Dev-Cpp forum.
+
+1 - Make a copy of (D:\Dev-Cpp\bin) bin folder and name it "bin Original"
+place it in the Dev-Cpp installed directory (D:\Dev-Cpp\ for this example)
+
+2 - Copy the entire contents of the LIB folder of curl-7.14.0.tar.gz or zip
+version into the bin folder above (D:\Dev-Cpp\bin). The reason being is that
+the make.exe file resides in this folder. Make.exe will use - Makefile.m32,
+Makefile.inc, and the source code included in the lib folder to compile the
+source code. There is a PATH issue with make.exe that remains unresolved at
+least for me. Unless the entire source code to be compiled is placed entirely
+within the directory of make.exe an error message will be generated - "file
+xxxx.yyy not available".
+
+3- Go to Dev-Cpp\bin and double click on make .exe. You will see a DOS window
+quickly pop up and close very quickly. Not to worry! Please do not skip this
+step.
+
+4- Click on the start button\Programs\MS-DOS Prompt.Once the DOS Window is up
+Type the disk drive letter (e.g. E: ) engage the enter button. The path should
+automatically take you to the directory of the make.exe file.
+
+5- To compile the source code simply type at the DOS prompt make -f
+Makefile.m32 as per instructions contained in the Makefile.m32 file (use any
+text processor to read instructions). I don't believe that this makefile
+allows for the option of non SSL. Ignore any warnings.
+
+6- Collect and make copies of libcurl.a, libcurl.dll, libcurldll.a and any *.o
+compilations you might need in another directory outside of the bin directory
+as you will need this files shortly to set up libcurl for use with
+Dev-cpp. For most apps *.o is not required. Later on we will show what to do
+with these files.
+
+7- You are finished but before closing we need to do cleanup - erase the bin
+folder and rename the "bin Original" folder created in step 1 to bin.
+
+Note to compile a curl executable the process is probably similar but instead
+of using the LIB folder contents use the SRC folder contents and Makefiles in
+curl-7.14.0.tar.gz. File directories relative placements must be respected for
+compiling to take place successfully. This may not be possible with the PATH
+problem that make.exe experiences. If anyone has solved this PATH issue and
+please make sure it actually works on Win 9x/2000/XP before letting me
+know. Then please let me or Daniel in on the solution so that it can be
+included with these instructions. Thanks.
+
+or
+
+Method II - Dev-Cpp GUI
+-----------------------
+
+1- Copy the entire contents of the LIB folder of curl-7.14.0.tar.gz or zip
+version into any folder outside of (Dev-Cpp\bin).
+
+2- Drop the File/New/click on Project.
+
+3- New Project Dialogue box appears. Double click on the Static Library.
+
+4- Create Project Dialogue box appears. Select the LIB folder location to
+place and locate your Project File Name. Placing the Project File Name
+elsewhere may cause problems (PATH issue problem again).
+
+5- Drop down the Project/Project Options. Project Options Dialogue box
+appears.
+
+6- Select the Makefile tab in the Project Options Dialogue Box. Check Box -
+Use Custom Makefile. Click on the Folder icon at the extreme right of the
+Check Box. Select Makefile.m32 in the folder wherever you have placed the
+contents of the LIB Folder. Press OK and close the Dialogue Box.
+
+7- Drop the Menu Project/Click on Add to Project. Open File Dialogue Box
+appears.  The Dialogue Box should open in the folder wherever you have placed
+the contents of the LIB Folder. If not go there.
+
+8- Select Crtl-A to select all files in the LIB folder. Click on open to add
+files and close box. Wait till all files are added. This may take 30 seconds
+or longer.
+
+9- Drop the Menu Execute/Click on Compile. 
+
+10- That's it.
+
+
+   The following steps must be completed if Curl is to work properly
+   =================================================================
+
+LIB folder inclusions (*.a placement)
+-------------------------------------
+
+1- Refer to Method I - DOS Command Line point # 6 Take libcurl.a, libcurldll.a
+and install it in the directory C( or whichever drive Dev is installed)
+:\Dev-Cpp\lib.
+
+
+Include Folder
+--------------
+
+1- Create a new folder by the name of curl (do not change the name curl to
+some other name as it will cause major issues) in the directory
+C:\Dev-Cpp\include.
+
+2- Copy the entire contents of the curl folder of curl-7.14.0.tar.gz or zip
+ version into the newly created curl directory - C:\Dev-Cpp\include\curl.
+
+Links To Include And Lib Folder
+-------------------------------
+
+1- Drop the Menu - Tools\Compiler Options\Directories\Libraries. Make sure
+that C( or whichever drive Dev is installed):\DEV-CPP\lib is included.
+
+2- Next select the Menu - Tools\Compiler Options\Directories\C Includes. Make
+sure that C:\DEV-CPP\include and C:\Dev-Cpp\include\curl are included.
+
+3- Next select the Menu - Tools\Compiler Options\Directories\C++
+Includes. Make sure that C:\DEV-CPP\include and C:\Dev-Cpp\include\curl are
+included.
+
+Linker Links
+------------
+
+1- Drop the Menu - Tools\Compiler Options\Directories\Compiler.
+
+2- Make sure that the box "Add these commands to the linker command line" is
+checked.
+
+3- Include in the white space immediately below the box referred in 2 -lcurl
+-lws2_32 -lwinmm.
+
+SSL Files
+---------
+
+1- Get the latest openSSL (as of time of this writing)
+openssl-0.9.7e-win32-bin.zip for the minimalist package of the openssl-0.9.7e
+binaries ported to MS Windows 95/98/NT/XP using the MingW32/GCC-3.1
+development environment. The file may be downloaded at
+http://curl.haxx.se/download/.
+
+2- Open the above zip file. You will find two files - SDL.dll,
+SDL_mixer.dll. Install them in the directory C:\WINDOWS\SYSTEM32 for Win 9x
+users and c:\winnt\system32 for NT-family users.
+
+Multithreading Files
+--------------------
+
+To be completed
+
+#define
+-------
+
+1- Make sure that your program includes the following - #define CURL_STATICLIB
+must be declared FIRST before any other define functions may be
+added. Otherwise you may experience link errors.
+
+2- Don't forget to include   #include "curl/curl.h".
+
+e.g.
+    #define CURL_STATICLIB 
+#include <windows.h>
+    #include "curl/curl.h"
+#include <fstream>
+#include <iostream>
+#include <vector>
+etc...
+
+
+Static or Dynamic Library
+-------------------------
+
+The above steps apply for the use by a static library. Should you choose to
+use a dynamic library you will be required to perform these additional steps.
+
+1- Refer to Method I - DOS Command Line point # 6. Install libcurl.dll in the
+directory C:\WINDOWS\SYSTEM32 for Win 9x users and c:\winnt\system32 for
+NT-family users.
+
+2- Refer to Linker Links point 3 - Replace -lcurl with -lcurldll.
+
+Voila you're done.
+
+The non-SSL static Library build may not be possible to use at least as of the
+time of this writing - v7.14. Check reference emails - Phillipe and I found it
+impossible to fully compile as certain files were missing for linking. No big
+loss as SSL is a major plus.
+
+Hope this Helps
+
