On July 15, Microsoft released SQL Server 2012 Service Pack 1 Cumulative Update 5. This is Build 11.0.3373, and I count 30 fixes in the public fix list. This CU is only for SQL Server 2012 Service Pack 1.
If you are running SQL Server 2012, I think you should be on Service Pack 1 by now. If you are on SQL Server 2012 Service Pack 1, I also think you should make an effort to stay on the latest Cumulative Update, even more so than for older versions of SQL Server, because of the large numbers of significant fixes that have been included in each Cumulative Update. The RTM release of SQL Server 2012 Service Pack 1 was released back on June 18, 2012, which is over a year ago now.
