Yesterday, Tenable's research group released Nessus plugin #22449 which can detect Windows systems that are missing a set of patches covered in Microsoft bulletin MS06-055. This patch fixes security issues related to Outlook and Internet Explorer's use of the Vector Markup Language APIs. Systems with this vulnerability are exposed to exploitation from visiting hostile web pages or receiving email designed to exploit the flaws in VML. The plugin is a patch audit and requires domain credentials to analyze the remote system. This plugin is available to all Direct Feed subscribers and Security Center users.
