high Nessus Plugin ID 306642

Synopsis

The remote Red Hat host is missing one or more security updates for buildah / crun / podman / runc / skopeo.

Description

The remote Redhat Enterprise Linux 9 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2026:8325 advisory.

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)
