Buffer overflow in TranslateFilename for common.c in MPlayer 1.0pre4 allows remote attackers to execute arbitrary code via a long file name.
The pnmgetchunk function in xine 0.99.2 and earlier, and other packages such as MPlayer that use the same code, does not properly verify that the chunk size is less than the PREAMBLESIZE, which causes a read operation with a negative length that leads to a buffer overflow via (1) RMFTAG, (2) DATATAG, (3) PROPTAG, (4) MDPRTAG, and (5) CONTTAG values, a different vulnerability than CVE-2004-1187.
Heap-based buffer overflow in the pnmgetchunk function for xine 0.99.2, and other packages such as MPlayer that use the same code, allows remote attackers to execute arbitrary code via long PNATAG values, a different vulnerability than CVE-2004-1188.
Buffer overflow in the getheader function in asfmmststreaming.c for MPlayer 1.0pre5 allows remote attackers to execute arbitrary code via a crafted ASF video stream.
Stack-based buffer overflow in the asfmmststreaming.c functionality for MPlayer 1.0pre5 allows remote attackers to execute arbitrary code via a large MMST stream packet.
Integer overflow in the realsetupandgetheader function in real.c for Unix MPlayer 1.0pre5 allows remote attackers to cause a denial of service (application crash) and possibly execute arbitrary code via a Real RTSP streaming media file with a -1 content-length field, which leads to a heap-based buffer overflow.
Buffer overflow in the HTTP parser for MPlayer 1.0pre3 and earlier, 0.90, and 0.91 allows remote attackers to execute arbitrary code via a long Location header.
Multiple buffer overflows in the Real-Time Streaming Protocol (RTSP) client for (1) MPlayer before 1.0pre4 and (2) xine lib (xine-lib) before 1-rc4, when playing Real RTSP (realrtsp) streams, allow remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via (a) long URLs, (b) long Real server responses, or (c) long Real Data Transport (RDT) packets.
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.
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 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.
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 heap-based buffer overflows in the code used to handle (1) MMS over TCP (MMST) streams or (2) RealMedia RTSP streams in xine-lib before 1.0, and other products that use xine-lib such as MPlayer 1.0pre6 and earlier, allow remote malicious servers to execute arbitrary code.
Multiple buffer overflows in asfhttprequest of MPlayer before 0.92 allows remote attackers to execute arbitrary code via an ASX header with a long hostname.
Buffer overflow in adpcm.c in MPlayer 1.0pre7 and earlier allows remote attackers to execute arbitrary code via crafted PCM audio data, as demonstrated using a video file with an audio header containing a large value in a stream format (strf) chunk.
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.
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.
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.
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.
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.
oCERT reported a vulnerability that affects the flic video codec support in ffmpeg. Quoting:
"The MPlayer package [1] is vulnerable to an arbitrary offset dereference vulnerability, which could be exploited by malicious remote attacker. The vulnerability is caused by the MPlayer's flic codec (flicvideo.c) on 8 bits per pixel videos because the codec does not check received values. This could be exploited jumping to arbitrary code by opening a specially crafted file."
They were particularly concerned about the ffmpeg inclusion in mplayer. The affected file (flicvideo.c) is also present in libextractor as provided by Fedora 12. It looks as though the only thing using libextractor in Fedora is doodle (local search program, like Spotlight). This would mean a user would have to download a specially crafted file and store it locally, and be using doodle to index files. I don't know whether or not doodle would be problematic here, i.e. if it's just reading metadata it might not cause any problems at all.
Later versions of libextractor have removed the embedded ffmpeg sources.
