Technical Summary
This advisory covers security updates in Red Hat OpenShift Container Platform 4.19.24 that fix three vulnerabilities: CVE-2025-15467 in OpenSSL allows remote code execution or denial of service via an oversized Initialization Vector in CMS parsing; CVE-2025-66293 in libpng causes an out-of-bounds read in png_image_read_composite; and CVE-2025-13601 in glib involves an integer overflow in g_escape_uri_string(). These vulnerabilities are rated as having important security impact by Red Hat Product Security. The update includes container images and RPM packages, and users should upgrade using the OpenShift CLI or web console. Detailed upgrade instructions and release notes are available from Red Hat. The affected versions are OpenShift Container Platform 4.19 prior to 4.19.24. No active exploitation has been reported.
Potential Impact
The vulnerabilities fixed in this update could allow remote code execution or denial of service (OpenSSL), out-of-bounds memory reads (libpng), and integer overflow issues (glib) within the OpenShift Container Platform environment. These issues could potentially compromise the confidentiality, integrity, or availability of affected systems if exploited. However, there are no known exploits in the wild at this time. The update addresses these security risks to protect OpenShift Container Platform deployments.
Mitigation Recommendations
Red Hat has released OpenShift Container Platform 4.19.24 containing fixes for these vulnerabilities. Users of OpenShift Container Platform 4.19 are strongly advised to upgrade to version 4.19.24 using the OpenShift CLI (oc) or web console as soon as the update is available in their release channel. Detailed upgrade instructions are provided by Red Hat in their official documentation. No additional mitigations are indicated beyond applying this update.
