Trillian IRC JOIN Remote Overflow

Medium Nessus Network Monitor Plugin ID 1872


The remote host is vulnerable to a buffer overflow.


The remote host is running the Trillian IRC client. Trillian versions 0.73, 0.74 and possibly other versions are vulnerable to a buffer overflow, caused by improper validation of JOIN commands received from an IRC server. If a Trillian client connects to an attacker-controlled IRC server and joins a channel with a name containing more than 206 characters, the attacker could overflow a buffer and cause the victim's Trillian client to crash or execute code on the system.


No solution is known at this time.
