Summary
Red Hat Security Advisory: Red Hat Product OCP Tools 4.17 OpenShift Jenkins security update

Notes

Topic
An update for OpenShift Jenkins is now available for Red Hat Product OCP Tools 4.17. Red Hat Product Security has rated this update as having a security impact of important. 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
Jenkins is a continuous integration server that monitors executions of repeated jobs, such as building a software project or jobs run by cron. Security Fix(es): * jenkins: HTTP/2 (including DNS over HTTPS) contains a design flaw and is vulnerable to "MadeYouReset" DoS attack through HTTP/2 control frames (CVE-2025-5115) 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.

The vulnerability arises from an implementation weakness in HTTP/2 stream reset handling \u2014 malformed client requests can trigger server-side resets without incrementing abuse counters, allowing an attacker to bypass built-in request throttling and overhead limits. Since these resets consume CPU and memory resources and can be generated at scale over a single TCP/TLS connection, a remote attacker could exhaust server capacity quickly, impacting all legitimate clients.",
