The remote host is vulnerable to a remote 'format string' flaw.
The remote host is running the Trillian IRC client. Trillian versions 0.725 and 0.73 are vulnerable to a format string attack in the IRC module. A remote attacker operating a malicious IRC server can deceive another user into joining a channel with a specially crafted name where malicious code can be stored. The malicious code could then be executed on the user's system, once the user joins the channel.
No solution is known at this time.
