Secondary Scheduler Operator for Red Hat OpenShift 1.2.2 for RHEL 9

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.

Description

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):

• Calling any of the Parse functions containing deeply nested literals can cause a panic/stack exhaustion (CVE-2024-34155)
• Calling Parse on a "// +build" build tag line with deeply nested expressions can cause a panic due to stack exhaustion (CVE-2024-34158)
• net/http: Denial of service due to improper 100-continue handling in net/http (CVE-2024-24791)
