A quick update:

I have recreated the Jenkins master and build nodes from backups, and have the new machines running. I am still waiting to hear from the NCSA security team concerning exactly what the vulnerability was.  I can't make Jenkins available publicly until we are confident that the vulnerability is not still exposed.

The same 5 tests that had been failing before are still failing, but I don't see any failures in McLachlan.
