DESCRIPTION:
Francis Provencher has discovered a vulnerability in IrfanView
Formats PlugIn, which can be exploited by malicious people to
compromise a user's system.

The vulnerability is caused due to a boundary error when processing
TTF font names and can be exploited to cause a stack-based buffer
overflow via a specially crafted font file.

Successful exploitation allows execution of arbitrary code, but
requires tricking a user into opening a malicious file.

The vulnerability is confirmed in version 4.33. Other versions may
also be affected.

SOLUTION:
Apply Formats PlugIn patch version 4.34.
