Description

A remote stack-based buffer overflow exists in Microsoft Internet Explorer. The browser's vml rendering engine fails to check the length of a fill parameter on the rect tag resulting in a stack-based buffer overflow. With a specially crafted request that contains a vml graphic, an attacker can cause arbitrary code execution resulting in a loss of integrity.
