Severity: Normal Title: GStreamer FFmpeg plugin: Heap-based buffer overflow Date: February 05, 2006 Bugs: #119512 ID: 200602-01

Synopsis ========
The GStreamer FFmpeg plugin is vulnerable to a buffer overflow that may be exploited by attackers to execute arbitrary code.
Background ==========
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.
Affected packages =================
------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 media-plugins/gst-plugins-ffmpeg < 0.8.7-r1 >= 0.8.7-r1
Description ===========
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.
Resolution ==========
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"
