Proof-of-concept (PoC) code for a security flaw in Docker, the popular containerization platform, is now public. Background On November 19, researchers at Unit 42, Palo Alto Networks’ research team, published their analysis of a severe vulnerability in the popular container deployment platform, Docker.

CVE-2019-14271: Proof of Concept for Docker Copy (docker cp) Vulnerability Released

In Docker 19.03.x before 19.03.1 linked against the GNU C Library (aka glibc), code injection can occur when the nsswitch facility dynamically loads a library inside a chroot that contains the contents of the container.

The remote SUSE Linux SLES15 / SLES_SAP15 / openSUSE 15 host has packages installed that are affected by multiple vulnerabilities as referenced in the SUSE-SU-2025:03545-1 advisory.

    Note this update contains a already fixed references mostly.

    - Remove git-core recommends on SLE to avoid pulling it in unnecessary. (bsc#1250508)

      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).

    - Include historical changelog data from before the docker-stable fork. The       initial changelog entry did technically provide all the necessary       information, but our CVE tracking tools do not understand how the package is       forked and so it seems that this package does not include fixes for ~12 years       of updates. So, include a copy of the original package's changelog up until       the fork point. bsc#1250596

    - Update to docker-buildx v0.25.0. Upstream changelog:
      <https://github.com/docker/buildx/releases/tag/v0.25.0>

    - Update to Go 1.23 for building now that upstream has switched their 23.0.x       LTSS to use Go 1.23.

    - Do not try to inject SUSEConnect secrets when in Rootless Docker mode, as       Docker does not have permission to access the host zypper credentials in this       mode (and unprivileged users cannot disable the feature using       /etc/docker/suse-secrets-enable.) bsc#1240150

    - Initial docker-stable fork, forked from Docker 24.0.7-ce release       (packaged on 2024-02-14). The original changelog is included below for       historical reference.

Tenable has extracted the preceding description block directly from the SUSE security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

The remote SUSE Linux SLES12 host has packages installed that are affected by multiple vulnerabilities as referenced in the SUSE-SU-2025:03540-1 advisory.

    - Remove git-core recommends on SLE. Most SLE systems have       installRecommends=yes by default and thus end up installing git with Docker.

There are packages installed that are affected by a vulnerability referenced in the following CVE:

  - In Docker 19.03.x before 19.03.1 linked against the GNU C Library (aka glibc), code injection can occur
    when the nsswitch facility dynamically loads a library inside a chroot that contains the contents of the
    container. (CVE-2019-14271)

The remote Oracle Linux 7 host has packages installed that are affected by multiple vulnerabilities as referenced in the ELSA-2019-4827 advisory.

    docker-engine     [19.03.1-1.0.0]
    - update to 19.03.1

    [19.03-0.0.1]
    - update to 19.03

Tenable has extracted the preceding description block directly from the Oracle Linux security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

An update of the docker package has been released.

Three security vulnerabilities have been discovered in the Docker container runtime: Insecure loading of NSS libraries in 'docker cp'could result in execution of code with root privileges, sensitive data could be logged in debug mode and there was a command injection vulnerability in the 'docker build' command.

This update for containerd, docker, docker-runc, golang-github-docker-libnetwork fixes the following issues :

Docker :

  - CVE-2019-14271: Fixed a code injection if the nsswitch     facility dynamically loaded a library inside a chroot     (bsc#1143409).

  - CVE-2019-13509: Fixed an information leak in the debug     log (bsc#1142160).

  - Update to version 19.03.1-ce, see changelog at     /usr/share/doc/packages/docker/CHANGELOG.md     (bsc#1142413, bsc#1139649).

runc :

  - Use %config(noreplace) for /etc/docker/daemon.json     (bsc#1138920).

  - Update to runc 425e105d5a03, which is required by Docker     (bsc#1139649).

containerd :
