Hi,
I had found some bugs about memory leak on libupnp-1.6.18.
It may lead to memory leak when calling ThreadPoolAdd() or
ThreadPoolAddPersistent() which does not return 0.
See the attachment for patch.

Suppose the UPnP device is listening on 192.168.1.102:49152. Use the following to send
garbage bytes to the device:
while true; do echo "\""; done | netcat 192.168.1.102 49152
The device just keeps receiving these bytes and its memory usage keeps growing.
Malicious client may exploit it to exhaust the device's memory.
The attached patch eliminates this possibility.

it seems to me that there is still something wrong:
1) the new is_qdtext_char() is incorrect.
There is a trap if char is implemented as signed char.
Suppose that c is '\xFF', it will be -1 when converted to an int.
By definition, c should be qdtext:
qdtext = <any TEXT except <">>
TEXT = <any OCTET except CTLs, but including LWS>
OCTET = <any 8-bit sequence of data>
2) the character after '\\' could be either part of a quoted-pair
(together with '\\'), or a normal qdtext, since '\\' itself can
be treated as a qdtext. This is equivalent to saying that the
character after '\\' in a quoted string could be ANY octet.
A patch based on the above two observations is attached.

In soap_ctrlpt.c, in function get_response_value:
upnp_error_code is checked to see if it is less than 400 because that
would indicate a SOAP error code.
However it should be checked to see if it is greater than 400.

Dear libupnp-devels,
when POST'ing to the simple web server in libupnp, the application crashes.
This is caused by a missing "..." argument in webserver.c:1533.
Seems it has been there for a long time ... 1.6.9 and 1.6.18 have it.
webserver.c:1533 calls http_MakeMessage
/* Send response. */
http_MakeMessage(&headers, 1, 1,
"RTLSXcCc",
ret, "text/html", X_USER_AGENT);
The format parameter RTLSXcCc needs four arguments -
R - response code - ret,
T- content type - text/html,
L - struct SendInstruction * - NOT PRESENT
X - user agent - X_USER_AGENT
This results in a crash.
Changing to
http_MakeMessage(&headers, 1, 1,
"RTLSXcCc",
ret, "text/html", &RespInstr, X_USER_AGENT);
solves the situation.
Yours,
Sebastian Brandt

Miniserver is disabled if ECXLUDE_GENA, EXCLUDE_SOAP and

So, MiniServer should not be disabled if EXCLUDE_SSDP is not also set.

There is a problem, perhaps, during downloading a document by
UpnpDownloadXmlDoc. During debugging i've found that in an not exported
api (unfortunately i forgot the code line...) where it is setted a
local variable "int timeout" to -1 then passed directly to another
function for sending data through tcp socket. I patched this setting it
to 0 (there is an IF section that exits if timeout < 0). It is normal
behavior or it is a bug?
Add infoSize parameter to get_sdk_info function to replace sprintf call
