Debian DSA-157-1 : irssi-text - denial of service

medium Nessus Plugin ID 14994

Synopsis

The remote Debian host is missing a security-related update.

Description

The IRC client irssi is vulnerable to a denial of service condition.
The problem occurs when a user attempts to join a channel that has an overly long topic description. When a certain string is appended to the topic, irssi will crash.

Solution

Upgrade the irssi-text package.

This problem has been fixed in version 0.8.4-3.1 for the current stable distribution (woody) and in version 0.8.5-2 for the unstable distribution (sid). The old stable distribution (potato) is not affected, since the corresponding portions of code are not present.
The same applies to irssi-gnome and irssi-gtk, which don't seem to be affected as well.
