Description

This update to python 2.6.8 fixes the following bugs, among others :

  • XMLRPC Server DoS. (CVE-2012-0845, bnc#747125)

  • hash randomization issues. (CVE-2012-1150, bnc#751718)

  • insecure creation of .pypirc. (CVE-2011-4944, bnc#754447)

  • SimpleHTTPServer XSS. (CVE-2011-1015, bnc#752375)

  • functions can accept unicode kwargs. (bnc#744287)

  • python MainThread lacks ident. (bnc#754547)

  • TypeError: waitpid() takes no keyword arguments. (bnc#751714)

  • Source code exposure in CGIHTTPServer module. (CVE-2011-1015, bnc#674646)

  • Insecure redirect processing in urllib2 (CVE-2011-1521, bnc#682554) The hash randomization fix is by default disabled to keep compatibility with existing python code when it extracts hashes.

To enable the hash seed randomization you can use: - pass -R to the python interpreter commandline. - set the environment variable PYTHONHASHSEED=random to enable it for programs. You can also set this environment variable to a fixed hash seed by specifying a integer value between 0 and MAX_UINT.

In generally enabling this is only needed when malicious third parties can inject values into your hash tables.

The update to 2.6.8 also provides many compatibility fixes with OpenStack.
