Scooped earlier this morning by Chris Nackers on our sister site, myITforum.com, Microsoft has released the Cumulative Update 2 (CU2) for ConfigMgr 2012 SP1. Since the scoop, Microsoft has released their "description of the update" KB Article that details all of the fixes included in the update, as well as provides the Hotfix download link.

You can find the KB Article (Article ID: 2854009) here: Description of Cumulative Update 2 for System Center 2012 Configuration Manager Service Pack 1

Note that the CU2 release completely replaces the CU1 release.
