SQL Server 2012 SP1: Sixth Cumulative Update (CU6) available

Some days ago, Microsoft published the sixth Cumulative Update (CU6) for Microsoft SQL Server 2012 Service Pack one, two months after the fifth one.
As usual, if this Cumulative Update solves an issue you are facing, install it quickly - otherwise, do not install it and just have a look at it.

Which issues are covered by this CU6?

It is a small CU, it contains only 23 Hotfixes, mainly for the Engine and Analysis Services:

  • 12 for the Engine
  • 10 for SSAS
  • 1 for SSRS
