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 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 :

  - CVE-2019-5736: Fixed a container breakout vulnerability     (bsc#1121967).

  - Update to containerd v1.2.6, which is required by docker     (bsc#1139649).

golang-github-docker-libnetwork :

  - Update to version     git.fc5a7d91d54cc98f64fc28f9e288b46a0bee756c, which is     required by docker (bsc#1142413, bsc#1139649).
