This indicates an attempt to exploit a memory-corruption vulnerability in Microsoft Internet Explorer.
This vulnerabiliy is due to the lack of adequate validations of the arguments provided to the "ComponentFromPoint()" function. It may allow remote attackers to execute arbitrary code in the context of IE. Failed exploit attempts will likely cause IE to crash, resulting in a denial-of-service condition.
Internet Explorer 5.01
Internet Explorer 6
Internet Explorer 6 Service Pack 1
