Date: December 02, 2008

ID: 200812-01

Synopsis

A vulnerability in OptiPNG might result in user-assisted execution of arbitrary code.

Background

OptiPNG is a PNG optimizer that recompresses image files to a smaller size, without losing any information.

Vulnerable: < 0.6.2
Unaffected: >= 0.6.2

Description

A buffer overflow in the BMP reader in OptiPNG has been reported.

Impact

A remote attacker could entice a user to process a specially crafted BMP image, possibly resulting in the execution of arbitrary code with the privileges of the user running the application, or a Denial of Service.

Workaround

There is no known workaround at this time.

Resolution
