Topic
An update for python-backports-ssl_match_hostname is now available for Red Hat Enterprise Linux 7.
Description
The python-backports-ssl_match_hostname package brings match_hostname() to users of earlier versions of Python.
The Secure Sockets layer is only actually secure if you check the hostname in the certificate returned by the server to which you are connecting, and verify that it matches the hostname you are trying to reach.
However, the matching logic, defined in RFC2818, can be a bit tricky to implement on your own. This package backports the match_hostname() function included in the ssl package in the Standard Library of Python 3.2 for performing this check instead of requiring every application to implement the check separately.
For detailed information on changes in this release, see the Red Hat Enterprise Linux 7.5 Release Notes linked from the References section.
Users of python-backports-ssl_match_hostname are advised to upgrade to these updated packages.
