Synopsis
========

Multiple vulnerabilities in multiple GStreamer plug-ins might allow for
the execution of arbitrary code.

Background
==========

The GStreamer plug-ins provide decoders to the GStreamer open source
media framework.

Affected packages
=================

    -------------------------------------------------------------------
     Package                           /   Vulnerable   /   Unaffected
    -------------------------------------------------------------------
  1  media-libs/gst-plugins-good            < 0.10.14       >= 0.10.14
  2  media-libs/gst-plugins-base            < 0.10.22       >= 0.10.22
  3  media-plugins/gst-plugins-libpng     < 0.10.14-r1   >= 0.10.14-r1
    -------------------------------------------------------------------
     3 affected packages on all of their supported architectures.
    -------------------------------------------------------------------

Description
===========

Multiple vulnerabilities have been reported in several GStreamer
plug-ins:

* Tobias Klein reported two heap-based buffer overflows and an array
  index error in the qtdemux_parse_samples() function in
  gst-plugins-good when processing a QuickTime media .mov file
  (CVE-2009-0386, CVE-2009-0387, CVE-2009-0397).

* Thomas Hoger of the Red Hat Security Response Team reported an
  integer overflow that can lead to a heap-based buffer overflow in the
  gst_vorbis_tag_add_coverart() function in gst-plugins-base when
  processing COVERART tags (CVE-2009-0586).

* Tielei Wang of ICST-ERCIS, Peking University reported multiple
  integer overflows leading to buffer overflows in gst-plugins-libpng
  when processing a PNG file (CVE-2009-1932).

Impact
======

A remote attacker could entice a user or automated system using a
GStreamer plug-in to process a specially crafted file, resulting in the
execution of arbitrary code or a Denial of Service.

Workaround
==========

There is no known workaround at this time.

Resolution
==========

All gst-plugins-good users should upgrade to the latest version:

    # emerge --sync
    # emerge --ask --oneshot -v ">=media-libs/gst-plugins-good-0.10.14"

All gst-plugins-base users should upgrade to the latest version:

    # emerge --sync
    # emerge --ask --oneshot -v ">=media-libs/gst-plugins-base-0.10.22"

All gst-plugins-libpng users should upgrade to the latest version:

    # emerge --sync
    # emerge -a -1 -v ">=media-plugins/gst-plugins-libpng-0.10.14-r1"
