Irssi Off-by-One Heap-Based Memory Corruption Vulnerability

Irssi is prone to an off-by-one, heap-based, memory-corruption vulnerability because it fails to properly bounds-check user-supplied data before copying it into a memory buffer. Attackers can exploit this issue to crash the vulnerable client, resulting in a denial-of-service condition. Given the nature of this issue, attackers may also be able to run arbitrary code within the context of the vulnerable application, but this has not been confirmed.

Mitigation:

Users should upgrade to the latest version of Irssi.
