UPDATED: After releasing a rash of more than a half-dozen security patches, Microsoft has announced just two patches are slated for this week.

Microsoft Office is scheduled to receive a patch on March 14 for what the software maker terms a "critical" flaw. The highest warning level used by Microsoft, critical security errors indicate an attacker could use the flaw to exploit a vulnerability capable of taking control of a system.

The second "important" patch addresses a problem in the Windows operating system. An important patch usually signals a vulnerability that could permit Denial-of-Service attacks.

Along with a non-security high-priority update, Microsoft said it will also update its Malicious Software Removal Tool.

The company did not release additional details, as is its custom, but provides advanced word to help users more effectively plan to deploy the patches, according to the firm.

The upcoming "patch Tuesday" follows a month where Microsoft released seven patches, covering Windows, Internet Explorer, Media Player and Power Point. Two of the patches addressed Media Player problems Microsoft believed to be critical.
