Ubuntu Security Notice (C) 2013-2016 Canonical, Inc. / NASL script (C) 2013-2016 Tenable Network Security, Inc.


Synopsis :

The remote Ubuntu host is missing one or more security-related
patches.

Description :

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. (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).

Note that Tenable Network Security has extracted the preceding
description block directly from the Ubuntu security advisory. Tenable
has attempted to automatically clean and format it as much as possible
without introducing additional issues.

Solution :

Update the affected python3.2 and / or python3.2-minimal packages.
