Microsoft has released an update for the System Center Endpoint protection client.
http://support.microsoft.com/kb/2865173/en-us?sd=rss&spid=1060
This updates actually includes two updates, apparently both has to be installed but I haven’t been able to find this in any documentation.
To update the existing clients you can use Automatic Client Upgrade found under Site Configuration – Sites – Hierarchy Settings
The update doesn’t seem to be available from Windows Update or Catalog.
After updating the clients they will report version 4.3.215.0
