Red Hat Security Advisory: Red Hat OpenShift Service Mesh 3.1.5
Red Hat OpenShift Service Mesh 3.1.5, which is based on the open source Istio project, addresses a variety of problems in a microservice architecture by creating a centralized point of control in an application. Fixes/Improvements: * Updated to Istio version 1.26.8 * OCSP Memory Leak Check BSSL-Compatability Security Fix(es): * istio-rhel9-operator: Excessive resource consumption when printing error string for host certificate validation in crypto/x509 (CVE-2025-61729) * istio-pilot-rhel9: Excessive resource consumption when printing error string for host certificate validation in crypto/x509 (CVE-2025-61729) * istio-cni-rhel9: Excessive resource consumption when printing error string for host certificate validation in crypto/x509 (CVE-2025-61729) * istio-cni-rhel9: Unbounded allocation when parsing GNU sparse map (CVE-2025-58183)
AI Analysis
Technical Summary
Red Hat OpenShift Service Mesh 3.1.5 incorporates security fixes for two main vulnerabilities: CVE-2025-58183, which is an unbounded memory allocation issue when parsing GNU sparse map in the istio-cni-rhel9 component, and CVE-2025-61729, which causes excessive resource consumption when printing error strings related to host certificate validation in crypto/x509 across multiple components (istio-rhel9-operator, istio-pilot-rhel9, and istio-cni-rhel9). These issues can lead to denial of service conditions due to resource exhaustion. The release updates the underlying Istio version to 1.26.8 and addresses these vulnerabilities by fixing the underlying resource handling bugs.
Potential Impact
The vulnerabilities cause excessive resource consumption and unbounded memory allocation, which can lead to denial of service by exhausting system resources in affected components of the Red Hat OpenShift Service Mesh. This impacts the stability and reliability of the service mesh in microservice architectures, potentially disrupting application communication and control.
Mitigation Recommendations
Red Hat has released OpenShift Service Mesh version 3.1.5 which includes fixes for these vulnerabilities. Users should upgrade to version 3.1.5 to remediate the issues. The vendor advisory confirms the availability of this official fix. No additional mitigation actions are indicated beyond applying the update.
