<p>An update that solves one vulnerability, contains two features and has three fixes can now be installed.</p>
<h2>Description:</h2>
<p>This update for docker fixes the following issues:</p>
<p>Changes in docker:</p>
<ul>
<li>
<p>Update to Docker 28.5.1-ce. See upstream changelog online at
<https://docs.docker.com/engine/release-notes/28/#2851></p>
</li>
<li>
<p>Update to Docker 28.5.0-ce. See upstream changelog online at
<https://docs.docker.com/engine/release-notes/28/#2850></p>
</li>
<li>
<p>Update to docker-buildx v0.29.0. Upstream changelog:
<https://github.com/docker/buildx/releases/tag/v0.29.0></p>
</li>
<li>
<p>Remove git-core recommends on SLE. Most SLE systems have
installRecommends=yes by default and thus end up installing git with Docker.
bsc#1250508</p>
</li>
</ul>
<p>This feature is mostly intended for developers ("docker build git://") so
most users already have the dependency installed, and the error when git is
missing is fairly straightforward (so they can easily figure out what they
need to install).</p>
<ul>
<li>
<p>Update to docker-buildx v0.28.0. Upstream changelog:
<https://github.com/docker/buildx/releases/tag/v0.28.0></p>
</li>
<li>
<p>Update to Docker 28.4.0-ce. See upstream changelog online at
<https://docs.docker.com/engine/release-notes/28/#2840></p>
</li>
<li>
<p>Fixes a nil pointer panic in "docker push". bsc#1248373</p>
</li>
<li>
<p>Update warnings and errors related to "docker buildx ..." so that they
reference our openSUSE docker-buildx packages.</p>
</li>
<li>
<p>Enable building docker-buildx for SLE15 systems with SUSEConnect secret
injection enabled. PED-12534 PED-8905 bsc#1247594</p>
</li>
</ul>
<p>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.</p>
<p>Users can silence the "docker build" warning by setting DOCKER_BUILDKIT=0
explicitly.</p>
<p>In order to inject SCC credentials with docker-buildx, users should use</p>
<pre><code>RUN --mount=type=secret,id=SCCcredentials zypper -n ...
</code></pre>
<p>in their Dockerfiles, and</p>
<pre><code>docker buildx build --secret id=SCCcredentials,src=/etc/zypp/credentials.d/SCCcredentials,type=file .
</code></pre>
<p>when doing their builds.</p>
<ul>
<li>
<p>Update to Docker 28.3.3-ce. See upstream changelog online at
<https://docs.docker.com/engine/release-notes/28/#2833>
CVE-2025-54388 bsc#1247367</p>
</li>
<li>
<p>Update to docker-buildx v0.26.1. Upstream changelog:
<https://github.com/docker/buildx/releases/tag/v0.26.1></p>
</li>
<li>
<p>Update to docker-buildx v0.26.0. Upstream changelog:
<https://github.com/docker/buildx/releases/tag/v0.26.0></p>
</li>
</ul>
