Summary0003664: m2crypto does not handle subjectAltName having non DNS:xxx entries
DescriptionVersion-Release number of selected component (if applicable):
0.16-6.el5.3

How reproducible:
All the time

Steps to Reproduce:
1. Get a SSL Certificate from IPSca for a yum repository
2. Setup the yum repository
3. Configure RHEL client to connect to the yum repository

Actual results:

M2Crypto.SSL.Checker.WrongHost: Peer certificate subjectAltName does not match
host, expected repo.tusk.tufts.edu, got email:tuskdev@elist.tufts.edu

Expected results:
Successfully connecting to the yum repository

Additional info:

According to the m2crypto comments in the code, it should only check against
the subjectAltName if the entry starts with DNS:, but it does not look like the
python code checks for it.

            # subjectAltName=DNS:somehost[, ...]*
            try:
                subjectAltName = peerCert.get_ext('subjectAltName').get_value()
                if not self._splitSubjectAltName(self.host, subjectAltName):
                    raise WrongHost(expectedHost=self.host,
                                    actualHost=subjectAltName,
                                    fieldName='subjectAltName')
                hostValidationPassed = True

I would suggest that you report this issue upstream at https://bugzilla.redhat.com/ - although I am not sure if yum is supposed to be able to work with that.

If you do report it upstream, please point us to the bug report there (and enter this bug report's number in the "foreign issue trackers" box on https://bugzilla.redhat.com/).

Thanks!

RedHat issued an update and errata fixing this problem:

http://rhn.redhat.com/errata/RHBA-2009-1351.html

Can we get m2crypto-0.16-6.el5.6 built and pushed to the CentOS yum repositories?

Yes, probably with the general updates after 5.4 has hit the shelves.
