http://security.gentoo.org/

Severity:	normal
Title:	GStreamer plug-ins: User-assisted execution of arbitrary code
Date:	07/12/2009
Bugs:	#256096, #261594, #272972
ID:	200907-11

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	Architecture(s)
media-libs/gst-plugins-good	< 0.10.14	>= 0.10.14	All supported architectures
media-libs/gst-plugins-base	< 0.10.22	>= 0.10.22	All supported architectures
media-plugins/gst-plugins-libpng	< 0.10.14-r1	>= 0.10.14-r1	All 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 --verbose ">=media-libs/gst-plugins-good-0.10.14"

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


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

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


    # emerge --sync
    # emerge --ask --oneshot --verbose ">=media-plugins/gst-plugins-libpng-0.10.14-r1"
