[FD] Divx plugin suite heap-based buffer overflow

[Andres Gomez Ramirez <andres.gomez@xxxxxxx>]

Introduction:

DirectShowDemuxFilter as part of Divx plugin suite is vulnerable to heap-based 
buffer overflow,
which can be exploited by malicious people to compromise a user's system. The 
vulnerability is
caused due to a signedness error in the processing of "STRF" (Stream Format) 
chunks.
This can be exploited to cause a heap-based buffer overflow via a specially 
crafted AVI file.
Successful exploitation may allow execution of arbitrary code by tricking a 
user into visiting a
malicious website.

DirectShowDemuxFilter is used by DivX Web Player, Divx Player and any 
application using
Divx plugins like Windows Media Player (When Divx is installed).
