CVE-2016-0772 (opens in a new tab)How to fix?
Upgrade RHEL:7 python33-python-tools to version 0:3.3.2-16.el7 or higher.
This issue was patched in RHSA-2016:1629.
NVD Description
Note: Versions mentioned in the description apply only to the upstream python33-python-tools package and not the python33-python-tools package as distributed by RHEL.
See How to fix? for RHEL:7 relevant fixed versions and status.
The smtplib library in CPython (aka Python) before 2.7.12, 3.x before 3.4.5, and 3.5.x before 3.5.2 does not return an error when StartTLS fails, which might allow man-in-the-middle attackers to bypass the TLS protections by leveraging a network position between the client and the registry to block the StartTLS command, aka a "StartTLS stripping attack."
