GLSA-200602-01 : GStreamer FFmpeg plugin: Heap-based buffer overflow

This script is Copyright (C) 2006-2014 Tenable Network Security, Inc.


Synopsis :

The remote Gentoo host is missing one or more security-related
patches.

Description :

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.

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 :

High / CVSS Base Score : 7.5
