Today's Microsoft "Patch Tuesday" brings six security bulletins that patch vulnerabilities in Microsoft Windows, Office, Internet Explorer and the Microsoft .NET Framework. It is the first regular patch day for Microsoft's newest operating system Windows 8 and Windows RT. Both systems are affected by three of the five bulletins that affect Windows or software built-in to Windows, just like Windows XP and Windows Server 2003 are. Windows Vista and Windows 7, as well as the server based operating systems Windows Server 2008 and 2008 R2, are addressed by all five Windows-related bulletins.
Four of the Windows related bulletins have received a maximum severity rating of critical, the highest possible rating. This means that at least one version of windows is affected by vulnerabilities describes in the bulletin as critical. The fifth Windows related bulletin has received a vulnerability rating of moderate, while the Office related bulletin one of important.
