Fix for CVE-2010-0433 where some kerberos enabled versions of OpenSSL
could be crashed if the relevant tables were not present (e.g. chrooted).

bec7184768 OR default SSL_OP_LEGACY_SERVER_CONNECT so existing options are preserved 2010-02-17 19:43:08 +00:00
Dr. Stephen Henson
442ac8d259 Allow renegotiation if SSL_OP_LEGACY_SERVER_CONNECT is set as well as 
initial connection to unpatched servers. There are no additional security
concerns in doing this as clients don't see renegotiation during an
attack anyway.

Since SSLv2 doesn't support renegotiation at all don't reject it if
legacy renegotiation isn't enabled.

Also can now use SSL2 compatible client hello because RFC5746 supports it.

More robust fix and workaround for PR#1949. Don't try to work out if there
is any write pending data as this can be unreliable: always flush.

Dr. Stephen Henson
5598b99fb3 The fix for PR#1949 unfortunately broke cases where the BIO_CTRL_WPENDING 
ctrl is incorrectly implemented (e.g. some versions of Apache). As a workaround
call both BIO_CTRL_INFO and BIO_CTRL_WPENDING if it returns zero. This should
both address the original bug and retain compatibility with the old behaviour.

c3c3b28818 Fix version handling so it can cope with a major version >3. 
Although it will be many years before TLS v2.0 or later appears old versions
of servers have a habit of hanging around for a considerable time so best
if we handle this properly now.

7a014dceb6 Add support for magic cipher suite value (MCSV). Make secure renegotiation 
work in SSLv3: initial handshake has no extensions but includes MCSV, if
server indicates RI support then renegotiation handshakes include RI.

NB: current MCSV value is bogus for testing only, will be updated when we
have an official value.

Change mismatch alerts to handshake_failure as required by spec.

Also have some debugging fprintfs so we can clearly see what is going on
if OPENSSL_RI_DEBUG is set.
