Summary
Red Hat Security Advisory: Red Hat OpenStack Services on OpenShift 18.0 (python-eventlet) security update

Notes

Topic
An update for python-eventlet is now available for Red Hat OpenStack Services on OpenShift 18.0 (Antelope). Red Hat Product Security has rated this update as having a security impact of Moderate. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section.
Details
Eventlet is a networking library written in Python. It achieves high scalability by using non-blocking io while at the same time retaining high programmer usability by using coroutines to make the non-blocking io operations appear blocking at the source code level. Security Fix(es): * Eventlet HTTP request smuggling (CVE-2025-58068) For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page listed in the References section.
