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

2.  Impact Information


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


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


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


There is no known workaround at this time.


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

Code Listing 3.1: Resolution

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