The company ran its Aok testing tool on the patch, and found that the MSO9-002 patch changes a large number of components. The ChangeBase report, which can be downloaded from ComputerWeekly.com states, "A very high proportion of applications are dependent on these changes. Organisations should seriously consider testing a good cross section of their application portfolio."
The MS09-002 patch fixes vulnerabilities that could allow remote code execution if a user views a specially crafted web page using Internet Explorer. Users whose accounts are configured to have fewer user rights on the system could be less impacted than users who operate with administrative user rights. Microsoft states that the update requires a restart.
