Yesterday, the “Microsoft Security Bulletin MS14-001” has been published.
It contains among others also security updates for SharePoint 2010 and SharePoint 2013.
Please note, that if these updates are deployed via WSUS to your SharePoint Servers, you must run the PSConfig wizard to complete the installation!
Please be aware that on automatic installation, the PSConfig Wiz. is not started automatically and therefore the patchlevel is not fully commited.In this case, the server runs still on the last build version although the higher CU build has been installed already.
Once the PSConfig wizard was executed, the patched buil level is applied successfully!
See the full Security bulletin for any further information.
