Developer’s Description

By Microsoft
Resolve the "Unchecked buffer in HTML Help can lead to Code Execution" security vulnerability in Windows XP to prevent a malicious user from running an unauthorized program on your computer.
The HTML Help facility in Windows includes an ActiveX control that provides much of its functionality. One of the functions that is exposed through the control contains an unchecked buffer. This buffer may be exploited by a Web page that is hosted on an attacker's site or that is sent to a user as an HTML message. An attacker who successfully exploits the vulnerability can run code in the security context of the user, and as a result, an attacker can gain the same privileges as the user on the computer.
