Trillian IRC Raw Message DoS

High

Synopsis

The remote host is vulnerable to a Denial of Service (DoS) attack.

Description

The remote host is running the Trillian IRC client. Trillian version 0.74 and possibly other versions are vulnerable to a Denial of Service attack, caused by improper validation of IRC raw messages. By sending one of the following raw requests: 206, 211, 213, 214, 215, 217, 218, 243, 302, 317, 324, 332, 333, 352, or 367, a remote attacker in control of a malicious IRC server could cause the victim's Trillian client to crash.

Solution

Upgrade or patch according to vendor recommendations.
