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

<vulnerable range="le">20071007-r4</vulnerable>
<p>Win32 Codecs is a set of Windows audio and video playback codecs.</p>
<p>A heap-based buffer overflow exists when handling Shockwave Flash files.</p>
<impact type="normal">
<p>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.
<p>There is no known workaround at this time.</p>
<p>Gentoo has discontinued support for Win32 Codecs. We recommend that
users unmerge Win32 Codecs:
# emerge --unmerge "media-libs/win32codecs"
