As you could notice this morning ,who will have WSUS activated
on your servers, the security bulletin MS12-066
 http://technet.microsoft.com/en-
us/security/bulletin/MS12-066 (KB 2741517) applies to SharePoint
2010 and MOSS 2007. That hotfix fix a vulnerability that allows
elevation of privileges.   As the hotfix is critical, it will be
installed automaticaly. So, after the installation, it's
mandatory to execute PSCONFIG on every single server of the
farm  => "psconfig –cmd upgrade –inplace b2b -wait" to complete
the update process.  Thank you.  Kind Regards..
