As expected, Microsoft today released its regular monthly batch of security bulletins and associated patches. This month there are twelve bulletins, addressing 57 identified vulnerabilities. (An additional bulletin has been added since the preview announcement last Thursday.) Five bulletins have a Critical severity rating, and seven are rated Important. Ten of the bulletins are for Windows and its components; every supported version of Windows is affected. All versions, except for the Server Core installation, have one or more Critical vulnerabilities.
There are also two bulletins that affect Microsoft server software: one, rated Critical, is for Exchange Server, and the other, rated Important, is for the FAST Search Server.
Microsoft says that seven of the Windows bulletins will definitely require a system restart. The other bulletins may require one, depending on the system’s configuration.
For more detailed information, and download links, please see the Microsoft Security Bulletin Summary for February 2013.
As usual, I recommend applying these patches to your systems as soon as you conveniently can.
