CRITICAL: Highly Critical

DESCRIPTION: Secunia Research has discovered a vulnerability in IrfanView's Formats plug-in, which can be exploited by malicious people to compromise a user's system. The vulnerability is confirmed in version 4.22. Other versions may also be affected.

The vulnerability is caused due to an integer overflow when processing XPM files with certain dimensions. This can be exploited to cause a heap-based buffer overflow by e.g. tricking a user into opening a specially crafted XPM file.

SOLUTION: Update to version 4.23.
