Background ========== MPlayer is a media player capable of handling multiple multimedia file formats. Affected packages ================= ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 media-video/mplayer < 1.0.20060217 >= 1.0.20060217 Description =========== MPlayer makes use of 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). Furthermore, AFI Security Research discovered two integer overflows in ASF file format decoding, in the new_demux_packet() function from libmpdemux/demuxer.h and the demux_asf_read_packet() function from libmpdemux/demux_asf.c. Impact ====== An attacker could craft a malicious media file which, when opened using MPlayer, would lead to a heap-based buffer overflow. This could result in the execution of arbitrary code with the permissions of the user running MPlayer. Workaround ========== There is no known workaround at this time. Resolution ========== All MPlayer users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose ">=media-video/mplayer-1.0.20060217" References ========== [ 1 ] CVE-2005-4048 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2005-4048 [ 2 ] CVE-2006-0579 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2006-0579 [ 3 ] 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-200603-03.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.
