Technical Summary
This advisory covers Red Hat OpenShift Container Platform 4.17.47, which addresses eight security vulnerabilities: CVE-2025-8677 (bind resource exhaustion via malformed DNSKEY), CVE-2025-40778 and CVE-2025-40780 (bind cache poisoning attacks), CVE-2025-59375 (libexpat large dynamic memory allocations via small XML documents), CVE-2025-5987 (libssh invalid return code for chacha20 poly1305 with OpenSSL backend), CVE-2025-9230 (openssl out-of-bounds read and write in RFC 3211 KEK unwrap), CVE-2025-9714 (libxslt infinite recursion in exsltDynMapFunction), and CVE-2025-11234 (qemu-kvm VNC WebSocket handshake use-after-free). The advisory provides updated container images and references RPM package updates. Users of OpenShift Container Platform 4.17 are recommended to upgrade to these updated images and packages to mitigate the vulnerabilities.
Potential Impact
The vulnerabilities fixed in this release can lead to resource exhaustion, cache poisoning, memory corruption, infinite recursion, and use-after-free conditions in critical components of the OpenShift Container Platform. These issues could potentially affect the stability, confidentiality, and integrity of the platform. The advisory rates the overall security impact as Important (high severity). There are no known exploits in the wild at the time of this advisory.
Mitigation Recommendations
A security update is available in Red Hat OpenShift Container Platform 4.17.47 that addresses these vulnerabilities. Users should upgrade to the updated container images and RPM packages through the appropriate release channels using the OpenShift CLI (oc) or web console. Detailed upgrade instructions are provided by Red Hat in their official documentation. No additional mitigation steps are indicated beyond applying the official update.
