Description Murray McAllister 2014-03-28 04:30:24 UTC
XChat did not verify that the server hostname matched the domain name in the subject's Common Name (CN) or subjectAltName field in X.509 certificates. This could allow a man-in-the-middle attacker to spoof an SSL server if they had a certificate that was valid for any domain name.

This was fixed in hexchat this past November:

https://github.com/hexchat/hexchat/commit/c9b63f7f9be01692b03fa15275135a4910a7e02d

It was originally reported in April 2013:

https://github.com/hexchat/hexchat/issues/524

I'm not sure if that means it should have a 2013 CVE or a 2014 one.  I am requesting one on oss-security.

Also, upstream XChat is no longer in active development.
