Summary


This security update resolves vulnerabilities in Windows. The most severe of the vulnerabilities could allow elevation of privilege if an attacker logs on to an affected system and runs a specially crafted application. An attacker who successfully exploited the vulnerability could run arbitrary code in the security context of the account of another user who is logged on to the affected system. An attacker could then install programs; view, change, or delete data; or create new accounts that have full user rights.

More Information


Known issues with this security update

  • Customers who are running supported editions of Windows Server 2003 are repeatedly reoffered security update 3033395. On March 16, 2015, Microsoft released update 3033395-v2 to address this problem. Customers who have not already installed the 3033395 update should install 3033395-v2 to be fully protected from this vulnerability. To avoid the possibility of future detection logic problems, we recommend that customers who are running Windows Server 2003 and who have already successfully installed update 3033395 also apply update 3033395-v2 even though their systems already have the protection that is provided by security update 3033395.
