Ubuntu Security Notice USN-3134-1
November 22, 2016

python2.7, python3.2, python3.4, python3.5 vulnerabilities

A security issue affects these releases of Ubuntu and its derivatives:

– Ubuntu 16.04 LTS
– Ubuntu 14.04 LTS
– Ubuntu 12.04 LTS


Several security issues were fixed in Python.

Software Description:
– python2.7: An interactive high-level object-oriented language
– python3.5: An interactive high-level object-oriented language
– python3.4: An interactive high-level object-oriented language
– python3.2: An interactive high-level object-oriented language


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)
