ALSA-2024:2055 — Important: buildah security update

Affected: AlmaLinux:9: buildah, AlmaLinux:9: buildah-tests

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):

* buildah: full container escape at build time (CVE-2024-1753)

Affected: CleanStart: buildah

Security vulnerability affects the buildah package. A flaw was found in Buildah (and subsequently Podman Build) which allows containers to mount arbitrary locations on the host filesystem into build containers.

EUVD-2026-375529

fkie_cve-2024-1753

A flaw was found in Buildah (and subsequently Podman Build) which allows containers to mount arbitrary locations on the host filesystem into build containers. A malicious Containerfile can use a dummy image with a symbolic link to the root filesystem as a mount source and cause the mount operation to mount the host root filesystem inside the RUN step. The commands inside the RUN step will then have read-write access to the host filesystem, allowing for full container escape at build time.

GHSA-874v-pj72-92f3 — Podman affected by CVE-2024-1753 container escape at build time

Affected: Go: github.com/containers/podman/v4, Go: github.com/containers/podman/v5

### Impact _What kind of vulnerability is it? Who is impacted?_

Users running containers with root privileges allowing a container to run with read/write access to the host system files when selinux is not enabled. With selinux enabled, some read access is allowed.

### Patches From @nalind . This is a patch for Buildah (https://github.com/containers/buildah). Once fixed there, Buildah will be vendored into Podman.

OESA-2025-1059 — buildah security update

Affected: openEuler:22.03-LTS-SP4: buildah

The package provides a command line tool which can be used to * create a working container from scratch or * create a working container from an image as a starting point * mount/umount a working container's root file system for manipulation * save container's root file system layer to create a new image * delete a working container or an image Security Fix(es): The crypto/tls package of Go through 1.16.5 does not properly assert that the type of public key in an X.509 certificate matches the expected type when doing a RSA based key exchange, allowing a malicious TLS server to cause a TLS client to panic.(CVE-2021-34558) Uncontrolled recursion in the Parse functions in go/parser before Go 1.17.12 and Go 1.18.4 allow an attacker to cause a panic due to stack exhaustion via deeply nested types or declarations.(CVE-2022-1962) An incorrect handling of the supplementary groups in the Buildah container engine might lead to the sensitive information disclosure or possible data modification if an attacker has direct access to the affected container where supplementary groups are used to set access permissions and is able to execute a binary code in that container.(CVE-2022-2990) Programs which compile regular expressions from untrusted sources may be vulnerable to memory exhaustion or denial of service. The parsed regexp representation is linear in the size of the input, but in some cases the constant factor can be as high as 40,000, making relatively small…
