BDA MPEG2 Transport Information Filter DLL side loading vulnerability
------------------------------------------------------------------------
Yorick Koster, September 2015

Abstract
------------------------------------------------------------------------
A DLL side loading vulnerability was found in the BDA MPEG2 Transport
Information Filter that ships with Windows Vista. This issue can be
exploited by loading the filter as an embedded OLE object. When
instantiating the object Windows will try to load the DLL ehTrace.dll
from the current working directory. If an attacker convinces the user to
open a specially crafted (Office) document from a directory also
containing the attacker's DLL file, it is possible to execute arbitrary
code with the privileges of the target user. This can potentially result
in the attacker taking complete control of the affected system.
