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" References ========== [ 1 ] CVE-2005-4048 http://www.cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2005-4048 [ 2 ] GLSA 200601-06 http://www.gentoo.org/security/en/glsa/glsa-200601-06.xml Availability ============ This GLSA and any updates to it are available for viewing at the Gentoo Security Website: http://security.gentoo.org/glsa/glsa-200602-01.xml Concerns? ========= Security is a primary focus of Gentoo Linux and ensuring the confidentiality and security of our users machines is of utmost importance to us.
