Description

The Active Template Library (ATL) in Microsoft Visual Studio .NET 2003 SP1, Visual Studio 2005 SP1 and 2008 Gold and SP1, and Visual C++ 2005 SP1 and 2008 Gold and SP1 does not properly enforce string termination, which allows remote attackers to obtain sensitive information via a crafted HTML document with an ATL (1) component or (2) control that triggers a buffer over-read, related to ATL headers and buffer allocation, aka "ATL Null String Vulnerability."
