Win32 Codecs: User-assisted execution of arbitrary code — GLSA 201312-11

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

Affected packages

Package media-libs/win32codecs on all architectures
Affected versions <= 20071007-r4
Unaffected versions

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.

Workaround

There is no known workaround at this time.

Resolution

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

 # emerge --unmerge "media-libs/win32codecs"
