TITLE:
InterVideo HomeTheater WinDVDX ActiveX Control Buffer Overflow

SECUNIA ADVISORY ID:
SA24710

VERIFY ADVISORY:
http://secunia.com/advisories/24710/

CRITICAL:
Highly critical

IMPACT:
System access

WHERE:
>From remote

SOFTWARE:
InterVideo Home Theater 2.x
http://secunia.com/product/13931/

DESCRIPTION:
Parvez Anwar has discovered a vulnerability in InterVideo Home
Theater, which can be exploited by malicious people to compromise a
user's system.

The vulnerability is caused due to a boundary error within the
WinDVDX ActiveX control when handling the "GetDiscType()" method.
This can be exploited to cause a stack-based buffer overflow by
passing an overly long string (greater than 260 bytes) as argument to
the affected method.

Successful exploitation allows execution of arbitrary code.

The vulnerability is reported in version 2.1.13.0 and confirmed in
version 2.5.13.58 incorporating WinDVDX.ocx version 1.0.0.1. Other
versions may also be affected.

SOLUTION:
Set the kill-bit on the affected ActiveX control.

PROVIDED AND/OR DISCOVERED BY:
