Technical Summary
This advisory covers security updates in Red Hat OpenShift Container Platform 4.16.57 that fix three vulnerabilities: CVE-2025-15467 in OpenSSL allowing remote code execution or denial of service via an oversized Initialization Vector in CMS parsing; CVE-2025-66293 in libpng causing an out-of-bounds read in png_image_read_composite; and CVE-2025-13601 in glib involving an integer overflow in g_escape_uri_string(). These vulnerabilities affect OpenShift Container Platform 4.16 versions prior to 4.16.57. The update includes container images and RPM packages to remediate these issues. Users should upgrade using the OpenShift CLI or web console following Red Hat's documented procedures. The advisory rates the security impact as Important (high severity).
Potential Impact
The vulnerabilities fixed in this update could lead to remote code execution or denial of service (OpenSSL), memory safety issues such as out-of-bounds reads (libpng), and integer overflow conditions (glib). These issues could potentially be exploited to compromise the confidentiality, integrity, or availability of systems running affected versions of OpenShift Container Platform 4.16. No active exploitation has been reported at this time.
Mitigation Recommendations
Red Hat has released OpenShift Container Platform 4.16.57 containing fixes for these vulnerabilities. Users running versions >=4.16.0 and <4.16.57 should upgrade to 4.16.57 as soon as it is available in their release channel. Upgrades can be performed via the OpenShift CLI (oc) or the web console following Red Hat's official upgrade documentation. No additional mitigation steps are indicated beyond applying this update.
