Who is Vulnerable?
Vulnerability Description	The Active Template Library (ATL) is a set of template-based C++ classes that simplify the programming of Component Object Model (COM) objects. Multiple remote code execution vulnerabilities have been reported in the Microsoft ATL. The vulnerabilities are due to an error in the Load method of the IPersistStreamInit interface and to a bug in the ATL header that could allow reading a variant from a stream and leaving the variant type read with an invalid variant. A remote attacker could exploit these issues by convincing a user to visit a malicious Web page. Successful exploitation of this issue could allow remote code execution on the affected system.
