Synopsis

A buffer overflow vulnerability in Win32 Codecs can potentially allow for user-assisted arbitrary code execution.

2.  Impact Information

Background

Win32 Codecs is a set of Windows audio and video playback codecs.

Description

A heap-based buffer overflow exists when handling Shockwave Flash files.

Impact

A remote attacker could entice a user to open a specially crafted Flash file using a package linked against Win32 Codecs, possibly resulting in execution of arbitrary code with the privileges of the process or a Denial of Service condition.

3.  Resolution Information

Workaround

There is no known workaround at this time.

Resolution

Gentoo has discontinued support for Win32 Codecs. We recommend that users unmerge Win32 Codecs:

Code Listing 3.1: Resolution
