Date: Thu, 8 Mar 2007 17:46:57 -0800

[Message part 1 (text/plain, inline)]

Package: xine-lib
Version: 1.1.2+dfsg-2
Severity: grave
Tags: patch, security

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.
