[German]Microsoft is not really having a good run with its security updates for Exchange Server 2016 and Exchange Server 2019.

[German]ACROS Security has developed a fix for a previously unknown 0-day vulnerability in the Mark of the Web security feature of Windows Server 2012 and Server 2012 R2. The fix is available to customers via a 0patch micro-patch and enables the affected installations to be secured.
