"From Red Hat Security Advisory 2006:0713 :

Updated Python packages are now available to correct a security issue
in Red Hat Enterprise Linux 3 and 4.

This update has been rated as having important security impact by the
Red Hat Security Response Team.

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

A flaw was discovered in the way that the Python repr() function
handled UTF-32/UCS-4 strings. If an application written in Python used
the repr() function on untrusted data, this could lead to a denial of
service or possibly allow the execution of arbitrary code with the
privileges of the Python application. (CVE-2006-4980)

In addition, this errata fixes a regression in the SimpleXMLRPCServer
backport for Red Hat Enterprise Linux 3 that was introduced with
RHSA-2005:109.

Users of Python should upgrade to these updated packages, which
contain a backported patch to correct this issue."
