Description

Updated Python packages are now available to correct a security issue.

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

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

An integer overflow flaw was found in Python's PCRE library that could be triggered by a maliciously crafted regular expression. On systems that accept arbitrary regular expressions from untrusted users, this could be exploited to execute arbitrary code with the privileges of the application using the library. The Common Vulnerabilities and Exposures project assigned the name CVE-2005-2491 to this issue.

Users of Python should upgrade to these updated packages, which contain a backported patch that is not vulnerable to this issue.
