Technical Summary
This advisory covers security fixes in Red Hat OpenShift Container Platform 4.16.30, specifically addressing three CVEs: CVE-2024-8508 (unbounded name compression in unbound leading to denial of service), CVE-2024-50312 (information disclosure via GraphQL introspection), and CVE-2024-45338 (non-linear parsing of case-insensitive content in golang.org/x/net/html). The update is delivered as container images and RPM packages. Red Hat rates the security impact as important and recommends all users of OpenShift Container Platform 4.16 upgrade to 4.16.30. The advisory includes references to official errata and release notes for further details and upgrade guidance.
Potential Impact
