RHSA-2011:0260 - Security Advisory

Topic

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.

Description

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.
