Severity:	normal
Title:	Win32 Codecs: User-assisted execution of arbitrary code
Date:	12/16/2013
Bugs:	#232999
ID:	201312-11

Synopsis

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

Background

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

Affected packages

Package	Vulnerable	Unaffected	Architecture(s)
media-libs/win32codecs	<= 20071007-r4		All supported architectures

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"
