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

high Nessus Plugin ID 20864

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'
