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.
