Description

This module exploits a buffer overflow in VLC media player VLC media player prior
to 2.0.0. The vulnerability is due to a dangerous use of sprintf which can result
in a stack buffer overflow when handling a malicious MMS URI.

This module uses the browser as attack vector. A specially crafted MMS URI is
used to trigger the overflow and get flow control through SEH overwrite. Control
is transferred to code located in the heap through a standard heap spray.

The module only targets IE6 and IE7 because no DEP/ASLR bypass has been provided.
