Buildah is a tool that facilitates building OCI images. From 1.38.1 until 1.43.2 and 1.44.0, TempDirForURL in define/types.go does not securely confine Git repository subdirectories to the downloaded build context, and downloadToDirectory and stdinToDirectory can follow a Dockerfile symlink left by a partially extracted tar archive. A malicious server supplying a Git repository or tar archive can cause files outside the build context directory to be included in the context or copied into the build. This issue is fixed in versions 1.43.2 and 1.44.0.

The remote Fedora 43 host has packages installed that are affected by a vulnerability as referenced in the FEDORA-2026-be3238ba3e advisory.

    Update to buildah 1.43.2 and podman 5.8.3

    Security fix for CVE-2026-44517

The version of FreeBSD installed on the remote host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the fe2e8bdc-ff48-4166-b285-59822c7cf473 advisory.

    The Podman developers report:
    Building a Dockerfile using an ADD or COPY instruction accessing               a malicious Git repository or tar archive could cause files outside               the build context directory to be included in the build context or               copied into the build.
