Background ========== MPlayer is a media player capable of playing multiple media formats. Affected packages ================= ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 media-video/mplayer < 1.0_rc1-r2 >= 1.0_rc1-r2 Description =========== When checking for matching asm rules in the asmrp.c code, the results are stored in a fixed-size array without boundary checks which may allow a buffer overflow. Impact ====== An attacker can entice a user to connect to a manipulated RTSP server resulting in a Denial of Service and possibly execution of arbitrary code. 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_rc1-r2" References ========== [ 1 ] Original Advisory http://www.mplayerhq.hu/design7/news.html#vuln14 [ 2 ] CVE-2006-6172 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2006-6172 Availability ============ This GLSA and any updates to it are available for viewing at the Gentoo Security Website: http://security.gentoo.org/glsa/glsa-200702-11.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.
