Summary
Red Hat Security Advisory: Secondary Scheduler Operator for Red Hat OpenShift 1.2.0

Notes

Topic
Secondary Scheduler Operator for Red Hat OpenShift 1.2.0
Details
The Secondary Scheduler Operator for Red Hat OpenShift is an optional operator that makes it possible to deploy a secondary scheduler by providing a scheduler image. You can run a scheduler with custom plugins without applying additional manifests, such as cluster roles and deployments. Security Fix(es): * golang: net/http, x/net/http2: rapid stream resets can cause excessive work (CVE-2023-39325) * HTTP/2: Multiple HTTP/2 enabled web servers are vulnerable to a DDoS attack (CVE-2023-44487) * golang: html/template: improper handling of HTML-like comments within script contexts (CVE-2023-39318) * golang: html/template: improper handling of special tags within script contexts (CVE-2023-39319) * golang: crypto/tls: panic when processing post-handshake message on QUIC connections (CVE-2023-39321) * golang: crypto/tls: lack of a limit on buffered post-handshake (CVE-2023-39322)
