IrfanView Formats PlugIn DJVU Image Processing Heap Buffer Overflow Vulnerability

The Formats PlugIn for IrfanView is prone to a remote heap-based buffer-overflow vulnerability because the software fails to properly bounds-check user-supplied input before copying it to an insufficiently sized memory buffer.

Successful exploits allow remote attackers to execute arbitrary code in the context of the vulnerable application. Failed exploit attempts will likely result in denial-of-service conditions.

Formats PlugIn 4.33 is vulnerable; other versions may also be affected.
