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
