Technical Summary
This advisory covers security updates in Red Hat OpenShift Container Platform 4.17.49 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 issues are rated as having important security impact. The update addresses these vulnerabilities by providing patched container images and RPM packages. Users running OpenShift Container Platform 4.17 versions earlier than 4.17.49 should upgrade to the fixed release to apply these security fixes.
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), which may lead to application crashes or potential exploitation. The severity is rated as high by Red Hat Product Security. No active exploitation has been reported. The impact affects users running OpenShift Container Platform 4.17 prior to 4.17.49.
Mitigation Recommendations
A fix is available in Red Hat OpenShift Container Platform version 4.17.49. All users running versions >=4.17.0 and <4.17.49 are strongly advised to upgrade to 4.17.49 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 this update.
