CVE-2016-0772

原始描述

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."

受影响的软件

• Python = 3.3.4= 3.5.0= 3.2.5= 3.2.3= 3.1.1= 3.4.1 精确匹配
