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
-------------------------------------------------------------------
1 media-libs/win32codecs <= 20071007-r4 Vulnerable!
-------------------------------------------------------------------
NOTE: Certain packages are still vulnerable. Users should migrate
to another package if one is available or wait for the
existing packages to be marked stable by their
architecture maintainers.

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"

References
