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:
Felipe Manzano and Anibal Sacco discovered a buffer overflow in the demuxer for MOV files.
Reimar Doeffinger discovered a buffer overflow in the FLAC header parsing.
Adam Bozanich discovered a buffer overflow in the CDDB access code.
Adam Bozanich discovered a buffer overflow in URL parsing.
The old stable distribution (sarge) doesn't contain mplayer.
For the stable distribution (etch), these problems have been fixed in version 1.0~rc1-12etch2.
We recommend that you upgrade your mplayer packages.
