Subject: Re: CVE Request -- Python SSL module does not handle
 certificates that contain hostnames with NULL bytes


I notice the upstream bug has patches for many versions of Python, but
not for Python 2.6.  Will a Python 2.6 patch be provided, or is it a
reasonable fix to just backport the patched 2.7 files to 2.6 directly?

Thanks,
