CVE-2016-0772 (opens in a new tab)How to fix?
Upgrade Oracle:6 python-libs to version 0:2.6.6-66.0.1.el6_8 or higher.
This issue was patched in ELSA-2016-1626.
NVD Description
Note: Versions mentioned in the description apply only to the upstream python-libs package and not the python-libs package as distributed by Oracle.
See How to fix? for Oracle:6 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."
