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.

Buffer overflow in the asmrpeval function in the RealMedia RTSP stream handler (asmrp.c) for Real Media input plugin, as used in (1) xine/xine-lib, (2) MPlayer 1.0rc1 and earlier, and possibly others, allows remote attackers to cause a denial of service and possibly execute arbitrary code via a rulebook with a large number of rulematches.

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.

Heap-based buffer overflow in libmpdemux/aviheader.c in MPlayer 1.0rc1 and earlier allows remote attackers to cause a denial of service (application crash) or possibly execute arbitrary code via a .avi file with certain large "indx truck size" and nEntriesInuse values, and a certain wLongsPerEntry value.

Multiple stack-based buffer overflows in stream/streamcddb.c in MPlayer before 1.0rc1try3 allow remote attackers to execute arbitrary code via a CDDB entry with a long (1) album title or (2) category.

The DirectShow loader (loader/dshow/DSVideoDecoder.c) in MPlayer 1.0rc1 and earlier, as used in xine-lib, does not set the biSize before use in a memcpy, which allows user-assisted remote attackers to cause a buffer overflow and possibly execute arbitrary code, a different vulnerability than CVE-2007-1246.

The DMOVideoDecoderOpen function in loader/dmo/DMOVideoDecoder.c in MPlayer 1.0rc1 and earlier, as used in xine-lib, does not set the biSize before use in a memcpy, which allows user-assisted remote attackers to cause a buffer overflow and possibly execute arbitrary code, a different vulnerability than CVE-2007-1387.
