"Multiple vulnerabilities has been discovered and corrected in python :

The _ssl module would always disable the CBC IV attack countermeasure
(CVE-2011-3389).

A flaw was found in the way the Python SimpleHTTPServer module
generated directory listings. An attacker able to upload a file with a
specially crafted name to a server could possibly perform a cross-site
scripting (XSS) attack against victims visiting a listing page
generated by SimpleHTTPServer, for a directory containing the crafted
file (if the victims were using certain web browsers) (CVE-2011-4940).

A race condition was found in the way the Python distutils module set
file permissions during the creation of the .pypirc file. If a local
user had access to the home directory of another user who is running
distutils, they could use this flaw to gain access to that user's
.pypirc file, which can contain usernames and passwords for code
repositories (CVE-2011-4944).

A flaw was found in the way the Python SimpleXMLRPCServer module
handled clients disconnecting prematurely. A remote attacker could use
this flaw to cause excessive CPU consumption on a server using
SimpleXMLRPCServer (CVE-2012-0845).

Hash table collisions CPU usage DoS for the embedded copy of expat
(CVE-2012-0876).

A denial of service flaw was found in the implementation of
associative arrays (dictionaries) in Python. An attacker able to
supply a large number of inputs to a Python application (such as HTTP
POST request parameters sent to a web application) that are used as
keys when inserting data into an array could trigger multiple hash
function collisions, making array operations take an excessive amount
of CPU time. To mitigate this issue, randomization has been added to
the hash function to reduce the chance of an attacker successfully
causing intentional collisions (CVE-2012-1150).

The updated packages have been patched to correct these issues.");
