CVE-2013-7449: Canonical Ubuntu Linux

Medium severity, CVSS 6.5. EPSS: 0.8% chance of exploitation in the next 30 days.

The ssl_do_connect function in common/server.c in HexChat before 2.10.2, XChat, and XChat-GNOME does not verify that the server hostname matches a domain name in the X.509 certificate, which allows man-in-the-middle attackers to spoof SSL servers via an arbitrary valid certificate.

Affected products

• Canonical Ubuntu Linux: version 12.04 only; version 14.04 only; version 15.10 only
• Hexchat Project Hexchat: up to and including 2.10.1
• Xchat Xchat: affected versions not specified
• Xchat Xchat Gnome: affected versions not specified
