ALSA-2023:6473 — Moderate: 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):

* golang: html/template: improper handling of JavaScript whitespace (CVE-2023-24540) * net/http, golang.org/x/net/http2: avoid quadratic complexity in HPACK decoding (CVE-2022-41723) * golang: crypto/tls: large handshake records may cause panics (CVE-2022-41724) * golang: net/http, mime/multipart: denial of service from excessive resource consumption (CVE-2022-41725) * golang: net/http, net/textproto: denial of service from excessive memory allocation (CVE-2023-24534) * golang: net/http, net/textproto, mime/multipart: denial of service from excessive resource consumption (CVE-2023-24536) * golang: html/template: backticks not treated as string delimiters (CVE-2023-24538) * golang: html/template: improper sanitization of CSS values (CVE-2023-24539) * containerd: Supplementary groups are not set up properly (CVE-2023-25173) * golang: html/template: improper handling of empty HTML attributes (CVE-2023-29400) * golang: net/http: insufficient sanitization of Host header (CVE-2023-29406)

CLEANSTART-2025-PN33710 — containerd is an open source container runtime

Affected: CleanStart: containerd

Security vulnerability affects the containerd package. containerd is an open source container runtime.

EUVD-2026-221558

fkie_cve-2023-25173

This bug has been fixed in containerd v1.6.18 and v.1.5.18. Users should update to these versions and recreate containers to resolve this issue. Users who rely on a downstream application that uses containerd's client library should check that application for a separate advisory and instructions. As a workaround, ensure that the `"USER $USERNAME"` Dockerfile instruction is not used. Instead, set the container entrypoint to a value similar to `ENTRYPOINT ["su", "-", "user"]` to allow `su` to properly set up supplementary groups.

GHSA-hmfx-3pcx-653p — Supplementary groups are not set up properly in github.com/containerd/containerd

Affected: Go: github.com/containerd/containerd

### Impact

A bug was found in containerd where supplementary groups are not set up properly inside a container. If an attacker has direct access to a container and manipulates their supplementary group access, they may be able to use supplementary group access to bypass primary group restrictions in some cases, potentially gaining access to sensitive information or gaining the ability to execute code in that container.

Downstream applications that use the containerd client library may be affected as well.

### Patches This bug has been fixed in containerd v1.6.18 and v.1.5.18. Users should update to these versions and recreate containers to resolve this issue. Users who rely on a downstream application that uses containerd's client library should check that application for a separate advisory and instructions.

### Workarounds

Ensure that the `"USER $USERNAME"` Dockerfile instruction is not used. Instead, set the container entrypoint to a value similar to `ENTRYPOINT ["su", "-", "user"]` to allow `su` to properly set up supplementary groups.

OESA-2023-1147 — containerd security update

Affected: openEuler:20.03-LTS-SP1: containerd, openEuler:20.03-LTS-SP3: containerd, openEuler:22.03-LTS: containerd, openEuler:22.03-LTS-SP1: containerd

containerd is an industry-standard container runtime with an emphasis on simplicity, robustness and portability. It is available as a daemon for Linux and Windows, which can manage the complete container lifecycle of its host system: image transfer and storage, container execution and supervision, low-level storage and network attachments, etc. Security Fix(es): containerd is an open source container runtime. Before versions 1.6.18 and 1.5.18, when importing an OCI image, there was no limit on the number of bytes read for certain files. A maliciously crafted image with a large file where a limit was not applied could cause a denial of service. This bug has been fixed in containerd 1.6.18 and 1.5.18. Users should update to these versions to resolve the issue. As a workaround, ensure that only trusted images are used and that only trusted users have permissions to import images.(CVE-2023-25153) containerd is an open source container runtime. A bug was found in containerd prior to versions 1.6.18 and 1.5.18 where supplementary groups are not set up properly inside a container. If an attacker has direct access to a container and manipulates their supplementary group access, they may be able to use supplementary group access to bypass primary group restrictions in some cases, potentially gaining access to sensitive information or gaining the ability to execute code in that container.
