Red Hat Security Advisory: buildah, crun, podman, runc, and skopeo security update
The buildah package provides a tool for facilitating building OCI container images. Among other things, buildah enables you to: Create a working container, either from scratch or using an image as a starting point; Create an image, either from a working container or using the instructions in a Dockerfile; Build both Docker and OCI images. Security Fix(es): * runc: container escape via 'masked path' abuse due to mount race conditions (CVE-2025-31133) * runc: container escape with malicious config due to /dev/console mount and related races (CVE-2025-52565) * runc: container escape and denial of service due to arbitrary write gadgets and procfs write redirects (CVE-2025-52881) * golang: archive/tar: Unbounded allocation when parsing GNU sparse map (CVE-2025-58183) * golang.org/x/crypto/ssh/agent: golang.org/x/crypto/ssh/agent: SSH client panic due to unexpected SSH_AGENT_SUCCESS (CVE-2025-47913) * github.com/sirupsen/logrus: github.com/sirupsen/logrus: Denial-of-Service due to large single-line payload (CVE-2025-65637) For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section.
AI Analysis
Technical Summary
This advisory covers security fixes in Red Hat OpenShift Container Platform 4.18.31, specifically addressing vulnerabilities in the runc container runtime. The fixed issues include container escape via 'masked path' abuse due to mount race conditions (CVE-2025-31133), container escape with malicious configuration exploiting /dev/console mount races (CVE-2025-52565), and container escape and denial of service caused by arbitrary write gadgets and procfs write redirects in opencontainers/selinux (CVE-2025-52881). These vulnerabilities could allow an attacker to escape container isolation or cause denial of service. The advisory provides updated RPM packages and container images to remediate these issues, and users are instructed to upgrade their OpenShift clusters accordingly.
Potential Impact
The vulnerabilities addressed in this advisory allow for container escape, which compromises container isolation, potentially enabling an attacker to execute code on the host system. Additionally, one vulnerability can cause denial of service. These impacts affect the security boundaries of containerized workloads on OpenShift Container Platform 4.18, posing a high security risk if exploited.
Mitigation Recommendations
Red Hat has released updated RPM packages and container images for OpenShift Container Platform 4.18.31 that fix these vulnerabilities. Users should upgrade to these updated packages and images via the appropriate release channels using the OpenShift CLI or web console. Detailed upgrade instructions are available in Red Hat's official documentation. No alternative mitigations or workarounds are indicated; applying the official update is required to remediate the issues.
