Hi Everyone,

When we went shopping for low cost/no cost certificates for the web server, 
I thought CAcert (https://www.cacert.org/) would meet our needs. The needs 
are modest:

(1) no domain names or DNS names in the CN
(2) multiple DNS names in the SAN
(3) "correct" KU and EKU uses
(4) low cost/no cost.

I was sadly mistaken because CAcert is using a long term CA certificate 
certified with MD5 (see below). I missed that when I was evaluating them, 
and I apologize for the massive gap. (We could overlook other faux pas on 
the issued end entity certificate, like KU of Key Agreement and the Server 
Gated Cryptography bits).

We're going to temporarily disable SSL on the web server.

They web server's key is still good, and it will be used in the future as 
part of a key continuity program.

If you installed the CAcert CA in a trust store, then you should promptly 
remove it.

Jeff
