Summary

Important: buildah security update

Details

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 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)

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.

CVE-2025-52881 (GCVE-0-2025-52881)

Vulnerability from cvelistv5 – Published: 2025-11-06 20:23 – Updated: 2025-11-06 21:07

Title

runc: LSM labels can be bypassed with malicious config using dummy procfs files

Summary

runc is a CLI tool for spawning and running containers according to the OCI specification. In versions 1.2.7, 1.3.2 and 1.4.0-rc.2, an attacker can trick runc into misdirecting writes to /proc to other procfs files through the use of a racing container with shared mounts (we have also verified this attack is possible to exploit using a standard Dockerfile with docker buildx build as that also permits triggering parallel execution of containers with custom shared mounts configured). This redirect could be through symbolic links in a tmpfs or theoretically other methods such as regular bind-mounts. While similar, the mitigation applied for the related CVE, CVE-2019-19921, was fairly limited and effectively only caused runc to verify that when LSM labels are written they are actually procfs files. This issue is fixed in versions 1.2.8, 1.3.3, and 1.4.0-rc.3.

CVE-2025-58183 (GCVE-0-2025-58183)

Vulnerability from cvelistv5 – Published: 2025-10-29 22:10 – Updated: 2025-11-04 21:13

Title

Unbounded allocation when parsing GNU sparse map in archive/tar

Summary

tar.Reader does not set a maximum size on the number of sparse region data blocks in GNU tar pax 1.0 sparse files. A maliciously-crafted archive containing a large number of sparse regions can cause a Reader to read an unbounded amount of data from the archive into memory. When reading from a compressed source, a small compressed input can result in large allocations.

Severity ?

4.3 (Medium)
