An attacker could use this flow to inject additional headers in a Python application that allows user provided header name or values. (CVE-2016-5699)

It was found that Python's smtplib library did not return an exception if StartTLS fails to establish correctly in the SMTP.starttls() function. An attacker with ability to launch an active man in the middle attack could strip out the STARTTLS command without generating an exception on the python SMTP client application, preventing the establishment of the TLS layer. (CVE-2016-0772)

A vulnerability was discovered in Python, in the built-in zipimporter. A specially crafted zip file placed in a module path such that it would be loaded by a later 'import' statement could cause a heap overflow, leading to arbitrary code execution. (CVE-2016-5636)");
