Customers with Microsoft Internet Security and Acceleration ISA Server or may also block malicious traffic intended to exploit this vulnerability. What is the scope of the vulnerability? If a user were logged on with administrative user rights, an attacker who successfully exploited this vulnerability could take complete control of an affected system. Users whose accounts are configured to have fewer user rights on the system could be less affected than users who operate with administrative user rights.
What causes the vulnerability? What is VML? Vector Markup Language VML is an XML-based exchange, editing, and delivery format for high-quality vector graphics on the Web that meets the needs of both productivity users and graphic design professionals. For more information on the VML, see the product documentation. What might an attacker use the vulnerability to do? An attacker who successfully exploited this vulnerability could take complete control of the affected system.
How could an attacker exploit the vulnerability? In a Web-based attack scenario, an attacker could host a Web site that contains a Web page that is used to exploit this vulnerability.
In addition, compromised Web sites and Web sites that accept or host user-provided content or advertisements could contain specially crafted content that could exploit this vulnerability. In all cases, however, an attacker would have no way to force users to visit these Web sites. Instead, an attacker would have to persuade users to visit the Web site, typically by getting them to click a link in an e-mail message or instant messenger message that takes users to the attacker's Web site.
In an e-mail based attack of this exploit, customers who read e-mail in plain text are at less risk from this vulnerability. Instead users would have to either click on a link that would take them to a malicious Web site or open an attachment to be at risk from this vulnerability.
Customers who read e-mail in plain text would also be at less risk when using the Outlook or Outlook Express preview panes. Filter by content: Additional information available. Sort by: Status Alphabetical. Expand all. Javascript is disabled.

An attacker could host a specially crafted Web site that is designed to exploit this vulnerability through Internet Explorer and then persuade a user to view the Web site.
This can also include compromised Web sites and Web sites that accept or host user-provided content or advertisements. These Web sites could contain specially crafted content that could exploit this vulnerability. In all cases, however, an attacker would have no way to force users to visit these Web sites. Instead, an attacker would have to persuade users to visit the Web site, typically by getting them to click a link in an e-mail message or in an Instant Messenger request that takes users to the attacker's Web site.
It could also be possible to display specially crafted Web content by using banner advertisements or by using other methods to deliver Web content to affected systems.
What systems are primarily at risk from the vulnerability? This vulnerability requires that a user is logged on and reading e-mail messages or is visiting Web sites for any malicious action to occur. Therefore, any systems where e-mail messages are read or where Internet Explorer is used frequently, such as workstations or terminal servers, are at the most risk from this vulnerability.
Systems that are not typically used to visit Web sites, such as most server systems, are at a reduced risk. What does the update do? The update changes the way that routines in the vector graphics link library, vgx. When this security bulletin was issued, had this vulnerability been publicly disclosed? Microsoft received information about this vulnerability through responsible disclosure. When this security bulletin was issued, had Microsoft received any reports that this vulnerability was being exploited?

To help customers better utilize the tool, detailed documentation will be provided with the tool.
There is also a version of the tool that offers an integrated experience for SMS administrators. Microsoft has created a version of the EST that will determine if you have to apply this update.
How can we run this command silently so that it requires no user interaction clicking OK on dialog boxes, etc. Another solutions I found from web and saying to ensure the below registry key been deleted from our registry.
Are they related to VGX. DLL unregistration process? Coz I still can see both keys on my registry list. Yes, the key is part of the registration process. If you look carefully, you will see they are two paths to the same location. Create a key under the first path and it appears under the second path. The solution we deployed has been posted above. Notice at the end of the script I added a check for the existence of a registry value then passed the result to the exit code.
