Summary
Security update for docker

Notes

Title of the patch
Security update for docker
Description of the patch
This update for docker fixes the following issues: Update to docker-buildx v0.28.0. See upstream changelog: <https://github.com/docker/buildx/releases/tag/v0.28.0> Update to Docker 28.4.0-ce. See upstream changelog: <https://docs.docker.com/engine/release-notes/28/#2840> - Update warnings and errors related to "docker buildx ..." so that they reference our openSUSE docker-buildx packages. - Enable building docker-buildx for SLE15 systems with SUSEConnect secret injection enabled.jsc#PED-12534jsc#PED-8905 bsc#1247594 As docker-buildx does not support our SUSEConnect secret injection (and some users depend "docker build" working transparently), patch the docker CLI so that "docker build" will no longer automatically call "docker buildx build", effectively making DOCKER_BUILDKIT=0 the default configuration. Users can manually use "docker buildx ..." commands or set DOCKER_BUILDKIT=1 in order to opt-in to using docker-buildx. Users can silence the "docker build" warning by setting DOCKER_BUILDKIT=0 explicitly. In order to inject SCC credentials with docker-buildx, users should use RUN --mount=type=secret,id=SCCcredentials zypper -n ... in their Dockerfiles, and docker buildx build --secret id=SCCcredentials,src=/etc/zypp/credentials.d/SCCcredentials,type=file . when doing their builds. Update to Docker 28.3.3-ce. See upstream changelog online at <https://docs.docker.com/engine/release-notes/28/#2833> Security issue fixed: - CVE-2025-54388: firewalld reload can make published container ports accessible from remote hosts (bsc#1247367) Update to docker-buildx v0.26.1. Upstream changelog: <https://github.com/docker/buildx/releases/tag/v0.26.1> Update to docker-buildx v0.26.0. Upstream changelog: <https://github.com/docker/buildx/releases/tag/v0.26.0>

          "text": "Moby is an open source container framework developed by Docker Inc. that is distributed as Docker Engine, Mirantis Container Runtime, and various other downstream projects/products. In versions 28.2.0 through 28.3.2, when the firewalld service is reloaded it removes all iptables rules including those created by Docker. While Docker should automatically recreate these rules, versions before 28.3.3 fail to recreate the specific rules that block external access to containers. This means that after a firewalld reload, containers with ports published to localhost (like 127.0.0.1:8080) become accessible from remote machines that have network routing to the Docker bridge, even though they should only be accessible from the host itself. The vulnerability only affects explicitly published ports - unpublished ports remain protected. This issue is fixed in version 28.3.3.",
