A stack-based buffer overflow vulnerability exists in MPlayer Lite r33064 due to improper bounds checking when handling M3U playlist files containing long http:// URL entries. An attacker can craft a malicious .m3u file with a specially formatted URL that triggers a stack overflow when processed by the player, particularly via drag-and-drop interaction. This flaw allows for control of the execution flow through SEH overwrite and a DEP bypass using a ROP chain that leverages known gadgets in loaded DLLs. Successful exploitation may result in arbitrary code execution with the privileges of the current user.

FFmpeg 0.5.x, as used in MPlayer and other products, allows remote attackers to cause a denial of service (application crash) or possibly execute arbitrary code via a malformed VC-1 file.

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.

NOTE: vector 5 might overlap CVE-2007-4938, and vector 6 might overlap CVE-2008-0486.

MPlayer allows remote attackers to cause a denial of service (application crash) via (1) a malformed AAC file, as demonstrated by lol-vlc.aac; or (2) a malformed Ogg Media (OGM) file, as demonstrated by lol-ffplay.ogm, different vectors than CVE-2007-6718.

Multiple integer underflows in the Real demuxer (demuxreal.c) in MPlayer 1.0rc2 and earlier allow remote attackers to cause a denial of service (process termination) and possibly execute arbitrary code via a crafted video file that causes the streamread function to read or write arbitrary memory.

Uncontrolled array index in the sdpplinparse function in stream/realrtsp/sdpplin.c in MPlayer 1.0 rc2 allows remote attackers to overwrite memory and execute arbitrary code via a large streamid SDP parameter. NOTE: this issue has been referred to as an integer overflow.

Buffer overflow in url.c in MPlayer 1.0rc2 and SVN before r25823 allows remote attackers to execute arbitrary code via a crafted URL that prevents the IPv6 parsing code from setting a pointer to NULL, which causes the buffer to be reused by the unescape code.

Buffer overflow in streamcddb.c in MPlayer 1.0rc2 and SVN before r25824 allows remote user-assisted attackers to execute arbitrary code via a CDDB database entry containing a long album title.

Common Vulnerabilities and Exposures assigned an identifier CVE-2008-0486 to the following vulnerability:

Array index vulnerability in libmpdemux/demuxaudio.c in MPlayer 1.0rc2 and SVN before r25917, and possibly earlier versions, as used in Xine-lib 1.1.10, might allow remote attackers to execute arbitrary code via a crafted FLAC tag, which triggers a buffer overflow.
