CVE-2014-9356

Una vulnerabilidad de salto de ruta en Docker versiones anteriores a 1.3.3, permite a atacantes remotos escribir en archivos arbitrarios y omitir un mecanismo de protección de contenedor por medio de un nombre de ruta completo en un enlace simbólico dentro una (1) imagen o (2) compilación en un Dockerfile.

It was found that a malicious container image could overwrite arbitrary portions of the host file system by including absolute symlinks, potentially leading to privilege escalation.

Docker is a service providing container management on Linux. It was found that a malicious container image could overwrite arbitrary portions of the host file system by including absolute symlinks, potentially leading to privilege escalation. A flaw was found in the way the Docker service unpacked images or builds after a "docker pull". An attacker could use this flaw to provide a malicious image or build that, when unpacked, would escalate their privileges on the system.
