Description

A remote overflow exists in RSA Authentication Agent for Web for IIS. IISWebAgentIF.dll fails to validate the length of the "url" parameter in the "Redirect" method, resulting in a stack-based buffer overflow. With a specially crafted GET request, an attacker can cause arbitrary code execution resulting in a loss of integrity.
