Several buffer overflows have been discovered in the MPlayer movie player, which might lead to the execution of arbitrary code. The Common Vulnerabilities and Exposures project identifies the following problems: CVE-2008-0485 Felipe Manzano and Anibal Sacco discovered a buffer overflow in the demuxer for MOV files. CVE-2008-0486 Reimar Doeffinger discovered a buffer overflow in the FLAC header parsing. CVE-2008-0629 Adam Bozanich discovered a buffer overflow in the CDDB access code. CVE-2008-0630 Adam Bozanich discovered a buffer overflow in URL parsing. For the stable distribution (etch), these problems have been fixed in version 1.0~rc1-12etch2. The old stable distribution (sarge) doesn't contain mplayer. We recommend that you upgrade your mplayer packages.
