TITLE:
3ivx MPEG-4 MP4 File Processing Buffer Overflows

SECUNIA ADVISORY ID:
SA27998

VERIFY ADVISORY:
http://secunia.com/advisories/27998/

CRITICAL:
Highly critical

IMPACT:
System access

WHERE:
>From remote

SOFTWARE:
3ivx MPEG-4 5.x
http://secunia.com/product/16851/

DESCRIPTION:
SYS 49152 has discovered some vulnerabilities in 3ivx MPEG-4, which
can be exploited by malicious people to compromise a user's system.

The vulnerabilities are caused due to boundary errors in
3ivxDSMediaSplitter.ax when processing certain atoms ("©art", "©nam",
"©cmt", "©des", and "©cpy") in MP4 files and can be exploited to cause
stack-based buffer overflows via a specially crafted MP4 file.

Successful exploitation allows execution of arbitrary code.

The vulnerabilities are confirmed in version 5.0.1 with the following
applications as attack vectors:
* Windows Media Player version 6.4.09.1130 (mplayer2.exe)
* Media Player Classic version 6.4.9.0

Other versions and applications may also be affected.

SOLUTION:
Do not open untrusted MP4 files.

PROVIDED AND/OR DISCOVERED BY:
