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"
