Risk: High
Microsoft's latest Patch Tuesday addressed six flaws - three critical, two important and one moderate.
Successful exploitation of all three critical flaws, which have been found in Excel, Windows Active Directory and the .NET framework, could result in remote code execution. The important flaws were found in Publisher and Internet Information Services and could also result in remote code execution if successfully exploited. The moderate flaw was found in Vista's Firewall and could result in information disclosure if successfully exploited.
