"Updated python packages that fix multiple security issues and three
bugs are now available for Red Hat Enterprise Linux 4.

The Red Hat Security Response Team has rated this update as having low
security impact. Common Vulnerability Scoring System (CVSS) base
scores, which give detailed severity ratings, are available for each
vulnerability from the CVE links in the References section.

Python is an interpreted, interactive, object-oriented programming
language.

Multiple flaws were found in the Python rgbimg module. If an
application written in Python was using the rgbimg module and loaded a
specially crafted SGI image file, it could cause the application to
crash or, possibly, execute arbitrary code with the privileges of the
user running the application. (CVE-2009-4134, CVE-2010-1449,
CVE-2010-1450)

This update also fixes the following bugs :

* Python 2.3.4's time.strptime() function did not correctly handle the
'%W' week number format string. This update backports the _strptime
implementation from Python 2.3.6, fixing this issue. (BZ#436001)

* Python 2.3.4's socket.htons() function returned
partially-uninitialized data on IBM System z, generally leading to
incorrect results. (BZ#513341)

* Python 2.3.4's pwd.getpwuid() and grp.getgrgid() functions did not
support the full range of user and group IDs on 64-bit architectures,
leading to 'OverflowError' exceptions for large input values. This
update adds support for the full range of user and group IDs on 64-bit
architectures. (BZ#497540)

Users of Python should upgrade to these updated packages, which
contain backported patches to correct these issues."
