error when StartTLS fails. A remote attacker could possibly use this to
expose sensitive information. (CVE-2016-0772)

Remi Rampin discovered that Python would not protect CGI applications
from contents of the HTTP_PROXY environment variable when based on
the contents of the Proxy header from HTTP requests. A remote attacker
could possibly use this to cause a CGI application to redirect outgoing
HTTP requests. (CVE-2016-1000110)

Insu Yun discovered an integer overflow in the zipimporter module in
Python that could lead to a heap-based overflow. An attacker could
use this to craft a special zip file that when read by Python could
possibly execute arbitrary code. (CVE-2016-5636)

Guido Vranken discovered that the urllib modules in Python did
not properly handle carriage return line feed (CRLF) in headers. A
remote attacker could use this to craft URLs that inject arbitrary
HTTP headers. This issue only affected Ubuntu 12.04 LTS and Ubuntu
14.04 LTS. (CVE-2016-5699)");
