Description

Details for this vulnerability have not been published by NIST at this point. Descriptions from software vendor advisories for this issue are provided below.

From USN-3134-1:

It was discovered that the smtplib library in Python did not return an

error when StartTLS fails. A remote attacker could possibly use this to

expose sensitive information. (CVE-2016-0772)

Rémi 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)
