Red Hat Security Advisory: Release of containers for RHOSO 18.0.21
Red Hat OpenStack Services on OpenShift is a hybrid cloud solution for deploying and managing virtualized and containerized applications in a scalable infrastructure with a Red Hat OpenShift Container Platform (RHOCP) control plane. Security Fix(es): * opencontainers/selinux: container escape and denial of service due to arbitrary write gadgets and procfs write redirects (CVE-2025-52881) * Go: Denial of Service vulnerability in certificate chain building (CVE-2026-32280) * pyasn1: Denial of Service due to memory exhaustion from malformed RELATIVE-OID (CVE-2026-23490) For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page listed in the References section.
AI Analysis
Technical Summary
The buildah package facilitates building OCI container images and is affected by two security vulnerabilities. CVE-2025-52881 is a runc vulnerability that allows container escape and denial of service through arbitrary write gadgets and procfs write redirects. CVE-2025-58183 is a golang archive/tar vulnerability causing unbounded memory allocation when parsing GNU sparse maps, potentially leading to denial of service. Red Hat has released security updates for buildah in Red Hat Enterprise Linux 9 to address these issues.
Potential Impact
Successful exploitation of CVE-2025-52881 could allow an attacker to escape container isolation and cause denial of service on the host system. CVE-2025-58183 could lead to denial of service due to unbounded memory allocation during tar archive processing. Both vulnerabilities pose a high security risk in environments using buildah for container image building.
Mitigation Recommendations
Red Hat has released updated buildah packages for Red Hat Enterprise Linux 9 that address these vulnerabilities. Users should apply the official security update as described in Red Hat advisory RHSA-2025:22011 and the referenced article https://access.redhat.com/articles/11258. No additional mitigation steps are indicated beyond applying the vendor-provided update.
