Summary
Red Hat Security Advisory: : Updated mod_python packages fix denial of service vulnerability

Notes

Topic
Updated mod_python packages that fix a denial of service vulnerability are now available for Red Hat Linux.
Details
mod_python embeds the Python language interpreter within the Apache httpd server. A bug has been found in mod_python versions 3.0.3 and earlier that can lead to a denial of service vulnerability. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CAN-2003-0973 to this issue. Although Red Hat Linux 9 shipped with a version of mod_python that contains this bug, our testing was unable to trigger the denial of service vulnerability. mod_python users are, however, advised to upgrade to these errata packages, which contain a backported patch that corrects this bug.
