libvpx is the VP8 codec SDK used to encode and decode video streams,
|
|
typically within a WebM format media file.

<description>
|
|
<p>
|
|
libvpx is vulnerable to an integer overflow vulnerability when
|
|
processing crafted VP8 video streams.
|
|
</p>

<impact type="normal">
|
|
<p>
|
|
A remote attacker could entice a user to open a specially crafted media
|
|
file, possibly resulting in the execution of arbitrary code with the
|
|
privileges of the user running the application, or a Denial of Service.
|
|
</p>
|
|
</impact>
|
|
<workaround>
|
|
<p>
|
|
There is no known workaround at this time.
|
|
</p>
|
|
</workaround>
|
|
<resolution>
|
|
<p>
|
|
All libvpx users should upgrade to the latest stable version:
|
|
</p>
|
|
<code>
|
|
# emerge --sync
|
|
# emerge --ask --oneshot --verbose ">=media-libs/libvpx-0.9.5"</code>
|
|
<p>
|
|
Packages which depend on this library may need to be recompiled. Tools
|
|
such as revdep-rebuild may assist in identifying some of these
|
|
packages.
