Vendor description
|
This security update resolves a privately disclosed vulnerability in Windows common controls. 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. The malicious file could be sent as an email attachment as well, but the attacker would have to convince the user to open the attachment in order to exploit the vulnerability.

SophosLabs comments
|
The exploit centers around the MSCOMCTL.OCX file and in particular, targets the MSCOMCTL.TreeView, MSCOMCTL.ListView2, MSCOMCTL.TreeView2, and MSCOMCTL.ListView controls. A specially crafted website can make use of this exploit by attempting to instantiate these controls with specifically designed exploited code. The effects of this vulnerability can be mitigated by setting the kill bit for the MSCOMCTL.TreeView, MSCOMCTL.ListView2, MSCOMCTL.TreeView2, and MSCOMCTL.ListView controls in the registry.
