CVE-2016-0772

CVE-2016-0772, medium severity (CVSS 6.5): 3 tracked apps concerned, all fixed or indeterminable on their current version.

Severity (CVSS): 6.5
Exploitation: 14.5 %
Tracked apps: 3
Still exposed: 0

Public exploit : ExploitDB Published on 2016-09-02

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."
