Microsoft Patches To Fix Five Critical Errors

Microsoft announced today that it plans to issue eight security patches that fix holes in its Windows operating system and Internet Explorer. The announcement came in advance of its monthly "Patch Tuesday" security release scheduled April 8.

Altogether, Microsoft is repairing five vulnerabilities deemed "critical" and three rated "important" in almost every version of its operating systems, including Windows Vista, Windows XP and Windows 2000, as well as Windows Server 2003 and Windows Server 2008, and Explorer.

The announcement was part of Microsoft's pre-patch notification, which was posted on the company's Web site today. Microsoft releases regularly scheduled patches on the second Tuesday of each month.

The five critical updates fix errors in Microsoft Office, Windows and Internet Explorer. All critical vulnerabilities can be exploited by remote code execution, which could allow an attacker to issue a denial of service attack or install malware to completely take over an affected system.

The three patches deemed important fix errors that enable hackers to "spoof" and gain unauthorized elevated privileges to different versions of Windows, as well as execute malicious code by exploiting an error found in Microsoft Office.
