Critical Microsoft patches coming Tuesday

IDG News Service - Microsoft Corp. on Tuesday plans to issue eight security alerts with patches, some critical, for Windows, Office, MSN Messenger and Exchange.
Five of the security bulletins apply to Windows, and at least one of those is deemed critical, Microsoft said in a notice posted to its Web site. Office, MSN Messenger and Exchange will get one bulletin each, all deemed critical, the company said.
In Microsoft's rating system for security issues, vulnerabilities that could allow a malicious Internet worm to spread without any action required on the part of the user are rated critical.
Microsoft gave no further information, other than that some of the patches for Windows will require restarting patched computers, as may the MSN Messenger patch. The fixes for Office and Exchange won't require users to restart the applications.
The software maker provides information in advance of its monthly patch-release day, every second Tuesday of the month, so users can prepare. Last month, Microsoft didn't release any patches after releasing a dozen security bulletins in February.
In addition to the patches, Microsoft on Tuesday through Windows Update plans to release an updated version of the Windows Malicious Software Removal Tool and two "high priority" updates for Windows that aren't related to security issues, the company said.
The Malicious Software Removal Tool detects and removes malicious code placed on computers.
