Background ========== Speex is an audio compression format designed for speech that is free of patent restrictions. Affected packages ================= ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 media-libs/speex < 1.2_beta3_p2 >= 1.2_beta3_p2 Description =========== oCERT reported that the Speex library does not properly validate the "mode" value it derives from Speex streams, allowing for array indexing vulnerabilities inside multiple player applications. Within Gentoo, xine-lib, VLC, gst-plugins-speex from the GStreamer Good Plug-ins, vorbis-tools, libfishsound, Sweep, SDL_sound, and speexdec were found to be vulnerable. Impact ====== A remote attacker could entice a user to open a specially crafted Speex file or network stream with an application listed above. This might lead to the execution of arbitrary code with privileges of the user playing the file. Workaround ========== There is no known workaround at this time. Resolution ========== All Speex users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose ">=media-libs/speex-1.2_beta3_p2" References ========== [ 1 ] CVE-2008-1686 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2008-1686 Availability ============ This GLSA and any updates to it are available for viewing at the Gentoo Security Website: http://security.gentoo.org/glsa/glsa-200804-17.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.
