Detail

Problem Description:

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.

2. Relevant releases/architectures:

Red Hat Enterprise Linux AS version 4 - i386, ia64, ppc, s390, s390x, x86_64 Red Hat Enterprise Linux Desktop version 4 - i386, x86_64 Red Hat Enterprise Linux ES version 4 - i386, ia64, x86_64 Red Hat Enterprise Linux WS version 4 - i386, ia64, x86_64

3. 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.

4. Solution:

Before applying this update, make sure all previously-released errata relevant to your system have been applied.

This update is available via the Red Hat Network. Details on how to use the Red Hat Network to apply this update are available at http://kbase.redhat.com/faq/docs/DOC-11259

5. Bugs fixed (http://bugzilla.redhat.com/):

497540 - grp module does not support whole uid/gid range 541698 - CVE-2009-4134 CVE-2010-1449 CVE-2010-1450 python: rgbimg: multiple security issues
