Bug description:
  http://www.openwall.com/lists/oss-security/2015/01/29/23

  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.

  Also applied to hexchat and xchat-gnome.
