Luigi Auriemma, Alin Rad Pop, Rémi Denis-Courmont, Quovodis, Guido Landi, Felipe Manzano, Anibal Sacco and others discovered multiple vulnerabilities in vlc, an application for playback and streaming of audio and video. In the worst case, these weaknesses permit a remote, unauthenticated attacker to execute arbitrary code with the privileges of the user running vlc. The Common Vulnerabilities and Exposures project identifies the following eight problems: CVE-2007-6681 A buffer overflow vulnerability in subtitle handling allows an attacker to execute arbitrary code through the opening of a maliciously crafted MicroDVD, SSA or Vplayer file. CVE-2007-6682 A format string vulnerability in the HTTP-based remote control facility of the vlc application allows a remote, unauthenticated attacker to execute arbitrary code. CVE-2007-6683 Insecure argument validation allows a remote attacker to overwrite arbitrary files writable by the user running vlc, if a maliciously crafted M3U playlist or MP3 audio file is opened. CVE-2008-0295, CVE-2008-0296 Heap buffer overflows in RTSP stream and session description protocol (SDP) handling allow an attacker to execute arbitrary code if a maliciously-crafted RTSP stream is played. CVE-2008-0073 Insufficient integer bounds checking in SDP handling allows the execution of arbitrary code through a maliciously crafted SDP stream ID parameter in an RTSP stream. CVE-2008-0984 Insufficient integrity checking in the MP4 demuxer allows a remote attacker to overwrite arbitrary memory and execute arbitrary code if a maliciously-crafted MP4 file is opened. CVE-2008-1489 An integer overflow vulnerability in MP4 handling allows a remote attacker to cause a heap buffer overflow, inducing a crash and possibly the execution of arbitrary code if a maliciously-crafted MP4 file is opened. For the stable distribution (etch), these problems have been fixed in version 0.8.6-svn20061012.debian-5.1+etch2. For the unstable distribution (sid), these problems have been fixed in version 0.6.8.e-2. We recommend that you upgrade your vlc packages.
