This August is bringing a record setting number of updates from Microsoft. In addition to last week’s LNK update, there will be another 14 bulletins addressing 34 vulnerabilities, that IT admins will have to take care of in the weeks after Patch Tuesday. Including the LNK update,9 bulletins have a rating of critical and affect all version of the Windows OS, Internet Explorer, Silverlight and Microsoft Office.
Windows 7 and 2008 R2 have a smaller number of critical vulnerabilities than Windows XP and 2003 in function of their improved security architecture, but are still affected by 2 critical vulnerabilities each.
Internet Explorer, Office and Silverlight updates apply across the board on all Windows versions. They are a examples of the this increasingly used type of flaw, where attackers and malware go through the installed applications rather than through the core operating system.
Windows XP SP2 users do not have any patches supplied to them, even though the 5 critical vulnerabilities for XP SP3 most likely apply to their discontinued version of the OS as well. Windows XP SP2 users should upgrade to SP3 as quickly as possible.
