http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2007-1246 says:
"The DMO_VideoDecoder_Open function in loader/dmo/DMO_VideoDecoder.c in
MPlayer 1.0rc1 and earlier 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."
xine-lib has a copy of this code in src/libw32dll/. Attached is the
(tiny) patch I used in Ubuntu for 1.1.2.
