Ubuntu 12.04 LTS / 14.04 LTS / 15.10 : xchat-gnome vulnerability (USN-2945-1)
High Nessus Plugin ID 90350
SynopsisThe remote Ubuntu host is missing a security-related patch.
DescriptionIt was discovered that XChat-GNOME incorrectly verified the hostname in an SSL certificate. An attacker could trick XChat-GNOME into trusting a rogue server's certificate, which was signed by a trusted certificate authority, to perform a man-in-the-middle attack.
Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
SolutionUpdate the affected xchat-gnome package.
