The GStreamer FFmpeg plugin uses code from the FFmpeg library to
|
|
provide fast colorspace conversion and multimedia decoders to the
|
|
GStreamer open source media framework.

<p>
|
|
The GStreamer FFmpeg plugin contains derived code from the FFmpeg
|
|
library, which is vulnerable to a heap overflow in the
|
|
"avcodec_default_get_buffer()" function discovered by Simon Kilvington
|
|
(see GLSA 200601-06).

<impact type="normal">
|
|
<p>
|
|
A remote attacker could entice a user to run an application using
|
|
the GStreamer FFmpeg plugin on a maliciously crafted PIX_FMT_PAL8
|
|
format image file (like PNG images), possibly leading to the execution
|
|
of arbitrary code with the permissions of the user running the
|
|
application.
|
|
</p>
|
|
</impact>
|
|
<workaround>
|
|
<p>
|
|
There is no known workaround at this time.
|
|
</p>
|
|
</workaround>
|
|
<resolution>
|
|
<p>
|
|
All GStreamer FFmpeg plugin users should upgrade to the latest
|
|
version:
|
|
</p>

<code>
|
|
# emerge --sync
|
|
# emerge --ask --oneshot --verbose ">=media-plugins/gst-plugins-ffmpeg-0.8.7-r1"</code>
