Red Hat Security Advisory: OpenShift Container Platform 4.13.63 bug fix and security update
Red Hat OpenShift Container Platform is Red Hat's cloud computing Kubernetes application platform solution designed for on-premise or private cloud deployments. This advisory contains the container images for Red Hat OpenShift Container Platform 4.13.63. See the following advisory for the RPM packages for this release: https://access.redhat.com/errata/RHSA-2026:0676 Space precludes documenting all of the container images in this advisory. See the following Release Notes documentation, which will be updated shortly for this release, for details about these changes: https://docs.redhat.com/en/documentation/openshift_container_platform/4.13/html/release_notes Security Fix(es): * libxslt: libxml2: Inifinite recursion at exsltDynMapFunction function in libexslt/dynamic.c (CVE-2025-9714) * expat: libexpat in Expat allows attackers to trigger large dynamic memory allocations via a small document that is submitted for parsing (CVE-2025-59375) * sssd: SSSD default Kerberos configuration allows privilege escalation on AD-joined Linux systems (CVE-2025-11561) * bind: Cache poisoning attacks with unsolicited RRs (CVE-2025-40778) * bind: Cache poisoning due to weak PRNG (CVE-2025-40780) * bind: Resource exhaustion via malformed DNSKEY handling (CVE-2025-8677) 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. All OpenShift Container Platform 4.13 users are advised to upgrade to these updated packages and images when they are available in the appropriate release channel. To check for available updates, use the OpenShift CLI (oc) or web console. Instructions for upgrading a cluster are available at https://docs.redhat.com/en/documentation/openshift_container_platform/4.13/html-single/updating_clusters/index#updating-cluster-within-minor.
AI Analysis
Technical Summary
This advisory covers Red Hat OpenShift Container Platform 4.13.63, which addresses six security vulnerabilities: CVE-2025-9714 (infinite recursion in libxslt/libxml2), CVE-2025-59375 (large memory allocation in expat), CVE-2025-11561 (privilege escalation via SSSD Kerberos configuration on AD-joined systems), CVE-2025-40778 and CVE-2025-40780 (cache poisoning attacks in bind due to unsolicited resource records and weak PRNG), and CVE-2025-8677 (resource exhaustion via malformed DNSKEY handling in bind). The advisory provides updated container images and references RPM package updates. Red Hat recommends upgrading OpenShift Container Platform 4.13 clusters using the OpenShift CLI or web console following official upgrade instructions.
Potential Impact
The vulnerabilities fixed in this update could allow attackers to cause denial of service through infinite recursion or resource exhaustion, trigger large memory allocations potentially impacting availability, escalate privileges on Active Directory-joined Linux systems, and perform DNS cache poisoning attacks. These issues affect core components used within OpenShift Container Platform, potentially impacting cluster stability, security, and trustworthiness of DNS responses. The overall security impact is rated as important by Red Hat.
Mitigation Recommendations
Red Hat has released updated container images and RPM packages for OpenShift Container Platform 4.13.63 that address these vulnerabilities. Users should upgrade their OpenShift clusters to this version using the OpenShift CLI (oc) or web console as soon as the updates are available in their release channels. Detailed upgrade instructions are provided in the official Red Hat documentation. No alternative mitigations are indicated; applying the official update is the recommended remediation.
