NVD Description

Note: Versions mentioned in the description apply only to the upstream python2.7 package and not the python2.7 package as distributed by Debian. See How to fix? for Debian:10 relevant fixed versions and status.

The ssl.match_hostname function in CPython (aka Python) before 2.7.9 and 3.x before 3.3.3 does not properly handle wildcards in hostnames, which might allow man-in-the-middle attackers to spoof servers via a crafted certificate.
