Background ========== Quote from http://mplayerhq.hu "MPlayer is a movie player for LINUX (runs on many other Unices, and non-x86 CPUs, see the documentation). It plays most MPEG, VOB, AVI, OGG/OGM, VIVO, ASF/WMA/WMV, QT/MOV/MP4, FLI, RM, NuppelVideo, YUV4MPEG, FILM, RoQ, PVA files, supported by many native, XAnim, and Win32 DLL codecs. You can watch VideoCD, SVCD, DVD, 3ivx, DivX 3/4/5 and even WMV movies, too." Affected packages ================= ------------------------------------------------------------------- Package/ Vulnerable / Unaffected ------------------------------------------------------------------- mplayer <= 0.92 >= 0.92-r1 mplayer <= mplayer-1.0_pre2 >= mplayer-1.0_pre2-r1 mplayer <= mplayer-1.0_pre3 >= mplayer-1.0_pre3-r3 Description =========== A vulnerability exists in the MPlayer HTTP parser which may allow an attacker to craft a special HTTP header ("Location:") which will trick MPlayer into executing arbitrary code on the user's computer. Impact ====== An attacker without privileges may exploit this vulnerability remotely, allowing arbitrary code to be executed in order to gain unauthorized access. Workaround ========== A workaround is not currently known for this issue. All users are advised to upgrade to the latest version of the affected package. Resolution ========== MPlayer may be upgraded as follows: x86 and sparc: # emerge sync # emerge -pv ">=media-video/mplayer-0.92-r1" # emerge ">=media-video/mplayer-0.92-r1" amd64: # emerge sync # emerge -pv ">=media-video/mplayer-1.0_pre2-r1" # emerge ">=media-video/mplayer-1.0_pre2-r1" ppc: # emerge sync # emerge -pv ">=media-video/mplayer-1.0_pre3-r2" # emerge ">=media-video/mplayer-1.0_pre3-r2" References ========== [ 1 ] http://www.mplayerhq.hu/homepage/design6/news.html 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. Any security concerns should be addressed to security () gentoo org or alternatively, you may file a bug at http://bugs.gentoo.org.
