For those people using Enterprise Vault to archive Exchange data, you will likely have heard about MS12-080.  Microsoft have just released patches to close the vulnerability for:

Exchange 2010 SP 2 - this is update rollup 5 v2

Exchange 2010 SP 1 - this is update rollup 8

Exchange 2007  SP 3 - this is update rollup 9

Of course there are other fixes in the updates, and whilst these aren't normally explicitly tested by Symantec, 'Update Rollups' are supported in the Symantec Enterprise Vault world.  The best way forward is to test them out in your own lab before deployment.
