Active Template Library (ATL) Security Updates



On Tuesday 28 July  we released guidance and updates to assist developers using our Active Template Library (ATL) to prevent creating controls or components with potential security vulnerabilities.  Vulnerabilities in libraries are a rare, but industry wide issue, that requires broad collaboration and action by the community at large to effectively resolve. 


Developers who have built controls using the ATL should take immediate action to review their control to identify if it is vulnerable and take appropriate action to rebuild their control using the updated ATL library and distribute a non-vulnerable version of their control to their customers.


If you develop any controls with ATL then please take a look at the guidance on MSDN detailing the steps required to identify and address affected controls. Also, we cover the issue in a Channel9 video.
