Windows Mail Find People DLL side loading vulnerability
------------------------------------------------------------------------
Yorick Koster, September 2015

Abstract
------------------------------------------------------------------------
A DLL side loading vulnerability was found in the Windows Mail Find
People DLL. This issue can be exploited by loading the "For &People..."
object as an embedded OLE object. When instantiating the object Windows
will try to load the DLL wab32res.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.
