Technical Summary
This advisory covers security fixes in Red Hat OpenShift Container Platform 4.16.58 for two Golang-related vulnerabilities. CVE-2025-61729 is a denial of service vulnerability due to excessive resource consumption triggered by a crafted certificate in the crypto/x509 package. CVE-2025-58183 is an unbounded allocation vulnerability in the archive/tar package when parsing GNU sparse map archives, which can lead to resource exhaustion. These vulnerabilities are rated as having an Important security impact by Red Hat Product Security. The advisory recommends upgrading OpenShift Container Platform 4.16 from versions >=4.16.0 and <4.16.58 to 4.16.58 to apply the fixes.
Potential Impact
Successful exploitation of CVE-2025-61729 can cause denial of service through excessive resource consumption when processing crafted certificates. CVE-2025-58183 can lead to unbounded memory allocation, potentially causing denial of service due to resource exhaustion when parsing malicious archive files. Both vulnerabilities affect the stability and availability of the OpenShift Container Platform 4.16 prior to 4.16.58.
Mitigation Recommendations
Red Hat has released OpenShift Container Platform 4.16.58 which includes fixes for these vulnerabilities. Users should upgrade to version 4.16.58 using the OpenShift CLI or web console as soon as the update is available in their release channel. Instructions for upgrading clusters are provided in Red Hat's official documentation. No alternative mitigations are specified; applying the official update is the recommended remediation.
