Summary
Red Hat Security Advisory: Self Node Remediation Operator 0.5.1 security update

Notes

Topic
This is an updated version of the Self Node Remediation Operator. This Operator is delivered by Red Hat Workload Availability. 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
The Self Node Remediation Operator works in conjunction with machine health check or node health check to provide automatic remediation of unhealthy nodes by rebooting them. This minimizes downtime for stateful applications and ReadWriteOnce (RWO) Volumes, as well as restoring compute capacity in the event of transient failures. Security Fix(es): * golang: net/http, x/net/http2: rapid stream resets can cause excessive work (CVE-2023-44487) (CVE-2023-39325) For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section.
