Summary
Red Hat Security Advisory: cert-manager Operator for Red Hat OpenShift 1.11.5

Notes

Topic
cert-manager Operator for Red Hat OpenShift 1.11.5 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 cert-manager Operator for Red Hat OpenShift builds on top of Kubernetes, introducing certificate authorities and certificates as first-class resource types in the Kubernetes API. This makes it possible to provide certificates-as-a-service to developers working within your Kubernetes cluster. Security Fix(es): * golang: net/http, x/net/http2: rapid stream resets can cause excessive work (Rapid Reset Attack) (CVE-2023-39325) A Red Hat Security Bulletin which addresses further details about the Rapid Reset flaw is available in the References section. * golang: crypto/tls: slow verification of certificate chains containing large RSA keys (CVE-2023-29409) 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.
