desc = 'The remote host is affected by the vulnerability described in GLSA-200602-01
(GStreamer FFmpeg plugin: Heap-based buffer overflow)
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
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.
Workaround
There is no known workaround at this time.

http://www.gentoo.org/security/en/glsa/glsa-200601-06.xml
Solution:
All GStreamer FFmpeg plugin users should upgrade to the latest
version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=media-plugins/gst-plugins-ffmpeg-0.8.7-r1"
Risk factor : Medium
