Updated python packages fix security vulnerabilities:

A vulnerability was reported in Python’s socket module, due to
a boundary error within the sock_recvfrom_into() function, which
could be exploited to cause a buffer overflow. This could be used
to crash a Python application that uses the socket.recvfrom_info()
function or, possibly, execute arbitrary code with the permissions
of the user running vulnerable Python code (CVE-2014-1912).

This updates the python package to version 2.7.6, which fixes several
other bugs, including denial of service flaws due to unbound readline()
calls in the ftplib and nntplib modules (CVE-2013-1752).

Denial of service flaws due to unbound readline() calls in the imaplib,
poplib, and smtplib modules (CVE-2013-1752).

A gzip bomb and unbound read denial of service flaw in python XMLRPC
library (CVE-2013-1753).

Python are susceptible to arbitrary process memory reading by a user
or adversary due to a bug in the _json module caused by insufficient
bounds checking. The bug is caused by allowing the user to supply a
negative value that is used an an array index, causing the scanstring
function to access process memory outside of the string it is intended
to access (CVE-2014-4616).

The CGIHTTPServer Python module does not properly handle URL-encoded
path separators in URLs. This may enable attackers to disclose a CGI
script’s source code or execute arbitrary scripts in the server’s
document root (CVE-2014-4650).

Python before 2.7.8 is vulnerable to an integer overflow in the buffer
type (CVE-2014-7185).

When Python’s standard library HTTP clients (httplib, urllib,
urllib2, xmlrpclib) are used to access resources with HTTPS, by
default the certificate is not checked against any trust store,
nor is the hostname in the certificate checked against the requested
host. It was possible to configure a trust root to be checked against,
however there were no faculties for hostname checking (CVE-2014-9365).

The python-pip and tix packages was added due to missing build
dependencies.
