           Summary: X.509 certificate for Bugzilla server(s) has expired
           Product: Wikimedia
           Version: unspecified
          Platform: All
               URL: https://bugzilla.wikimedia.org/
        OS/Version: All
            Status: NEW
          Keywords: shell
          Severity: normal
          Priority: Normal
         Component: Bugzilla
        AssignedTo: [email protected]
        ReportedBy: [email protected]

The X.509 certificate for bugzilla.wikimedia.org has expired: it is not valid
after 2011-01-31T21:36:50+00:00. It should be replaced.


Side notes:

It also uses the MD5 algorithm for hashing, which is not considered secure
anymore. This should be changed to a more secure algorithm like one from the
SHA-2 family.

The certificate is also used for bugs.wikimedia.org, but does not contain that
host name in the certificate (should be included in subjectAlternativeName as a
dNSName). bugs.wikimedia.org uses a HTTP 302 Moved to redirect users to
bugzilla.wikimedia.org, but this does not mean that the certificate does not
have to include the host name as well. (Or a second certificate has to be
used.)

Furthermore, I recommend restricting keyUsage to
critical:(digitalSignature,keyEncipherment) (this will limit the usable
algorithms to the ones with ephemeral keys, which should not be a problem, but
considered a good thing) and extendedKeyUsage to (serverAuth). Client
authentication is probably unnecessary for the certificate.
