Gentoo Linux Security Advisory

Title: GStreamer plug-ins: User-assisted execution of arbitrary code (GLSA 200907-11)
Severity: normal
Exploitable: remote
Date: July 12, 2009
Bug(s): #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: media-libs/gst-plugins-good
Vulnerable: < 0.10.14
Unaffected: >= 0.10.14
Architectures: All supported architectures

Package: media-libs/gst-plugins-base
Vulnerable: < 0.10.22
Unaffected: >= 0.10.22
Architectures: All supported architectures

Package: media-plugins/gst-plugins-libpng
Vulnerable: < 0.10.14-r1
Unaffected: >= 0.10.14-r1
Architectures: 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:
Code:
# 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:
Code:
# 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:
Code:
# emerge --sync
# emerge --ask --oneshot --verbose ">=media-plugins/gst-plugins-libpng-0.10.14-r1"
