Detail

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

- Ubuntu 13.04 - Ubuntu 12.10 - Ubuntu 12.04 LTS

Summary:

Several security issues were fixed in Python.

Software Description: - python2.7: An interactive high-level object-oriented language

Details:

Florian Weimer discovered that Python incorrectly handled matching multiple wildcards in ssl certificate hostnames. An attacker could exploit this to cause Python to consume resources, resulting in a denial of service. This issue only affected Ubuntu 13.04. (CVE-2013-2099)

Ryan Sleevi discovered that Python did not properly handle certificates with NULL characters in the Subject Alternative Name field. An attacker could exploit this to perform a man in the middle attack to view sensitive information or alter encrypted communications. (CVE-2013-4238)

Update instructions:

The problem can be corrected by updating your system to the following package versions:

Ubuntu 13.04:
python2.7 2.7.4-2ubuntu3.2
python2.7-minimal 2.7.4-2ubuntu3.2

Ubuntu 12.10:
python2.7 2.7.3-5ubuntu4.3
python2.7-minimal 2.7.3-5ubuntu4.3

Ubuntu 12.04 LTS:
python2.7 2.7.3-0ubuntu3.4
python2.7-minimal 2.7.3-0ubuntu3.4

In general, a standard system update will make all the necessary changes.
