Detailed Description

Business Impact:

This security update resolves a publicly disclosed vulnerability in the MSCOMCTL.OCX ActiveX control. The vulnerability could allow remote code execution if a user visits a website containing specially crafted content designed to exploit the vulnerability. In all cases, however, an attacker would have no way to force users to visit such a website. Instead, an attacker would have to convince users to visit the website, typically by getting them to click a link in an email message or Instant Messenger message that takes them to the attacker's website.

Technical Description:

A privately disclosed vulnerability in the widely deployed Microsoft Common Controls ActiveX control (MSCOMCTL.OCX) can be exploited for remote code execution.  The ListView, ListView2, TreeView and TreeView2 controls can be abused to run attacker supplied code in the context of the current user.  Exploitation of this vulnerability has a very wide attack surface.  These ActiveX controls can be embedded in documents such as Microsoft Word documents, Microsoft Excel documents and RTF files as well as be embedded in web pages.  It is recommended to immediately apply this update due to the likelihood of widespread exploitation.

Remediation: A patch is available, see references below for details.
