Stack-based buffer overflow in the demuxopenvqf function in libmpdemux/demuxvqf.c in MPlayer 1.0 rc2 before r28150 allows remote attackers to execute arbitrary code via a malformed TwinVQ file.

MPlayer, possibly 1.0rc1, allows remote attackers to cause a denial of service (SIGSEGV and application crash) via (1) a malformed MP3 file, as demonstrated by lol-mplayer.mp3; (2) a malformed Ogg Vorbis file, as demonstrated by lol-mplayer.ogg; (3) a malformed MPEG-1 file, as demonstrated by lol-mplayer.mpg; (4) a malformed MPEG-2 file, as demonstrated by lol-mplayer.m2v; (5) a malformed MPEG-4 AVI file, as demonstrated by lol-mplayer.avi; (6) a malformed FLAC file, as demonstrated by lol-mplayer.flac; (7) a malformed Ogg Theora file, as demonstrated by lol-mplayer.ogm; (8) a malformed WMV file, as demonstrated by lol-mplayer.wmv; or (9) a malformed AAC file, as demonstrated by lol-mplayer.aac. NOTE: vector 5 might overlap CVE-2007-4938, and vector 6 might overlap CVE-2008-0486.

Multiple integer overflows in MPlayer 1.0pre7try2 allow remote attackers to cause a denial of service and trigger heap-based buffer overflows via (1) a certain ASF file handled by asfheader.c that causes the asfdescrambling function to be passed a negative integer after the conversion from a char to an int or (2) an AVI file with a crafted wLongsPerEntry or nEntriesInUse value in the indx chunk, which is handled in aviheader.c.

Multiple integer overflows in (1) the newdemuxpacket function in demuxer.h and (2) the demuxasfreadpacket function in demuxasf.c in MPlayer 1.0pre7try2 and earlier allow remote attackers to execute arbitrary code via an ASF file with a large packet length value. NOTE: the provenance of this information is unknown; portions of the details are obtained from third party information.
