man-in-the-middle attackers to spoof SSL servers via an arbitrary valid
certificate. (CVE-2014-9365)

Security Advisory Recommended Actions

If you are running a version listed in the Versions known to be vulnerable
column, you can eliminate this vulnerability by upgrading to a version listed
in the Fixes introduced in column. If the table lists only an older version
than what you are currently running, or does not list a non-vulnerable version,
then no upgrade candidate currently exists.

Mitigation

To mitigate this vulnerability, ensure Python scripts communicate only with
trusted servers. Manually download and install update packages instead of using
automatic update scripts that access external update servers.
