Descriptions

The docker packages version docker-1.13.1-108.git4ef4b30.el7 as released for Red Hat Enterprise Linux 7 Extras via RHBA-2020:0053 (https://access.redhat.com/errata/RHBA-2020:0053) included an incorrect version of runc that was missing multiple bug and security fixes. One of the fixes regressed in that update was the fix for CVE-2016-9962, that was previously corrected in the docker packages in Red Hat Enterprise Linux 7 Extras via RHSA-2017:0116 (https://access.redhat.com/errata/RHSA-2017:0116). The CVE-2020-14300 was assigned to this security regression and it is specific to the docker packages produced by Red Hat. The original issue - CVE-2016-9962 - could possibly allow a process inside container to compromise a process entering container namespace and execute arbitrary code outside of the container. This could lead to compromise of the container host or other containers running on the same container host. This issue only affects a single version of Docker, 1.13.1-108.git4ef4b30, shipped in Red Hat Enterprise Linux 7. Both earlier and later versions are not affected.

La versión de los paquetes docker docker-1.13.1-108.git4ef4b30.el7 según lo publicado para Red Hat Enterprise Linux 7 Extras por medio de RHBA-2020:0053 (https://access.redhat.com/errata/RHBA-2020:0053) incluida una versión incorrecta de runc a la que le faltaban múltiples correcciones de bugs y seguridad. Una de las correcciones regresadas en esa actualización fue la corrección para CVE-2016-9962, que se corrigió previamente en los paquetes docker en Red Hat Enterprise Linux 7 Extras por medio de RHSA-2017:0116 (https://access.redhat.com/errata/RHSA-2017:0116). El CVE-2020-14300 fue asignado a esta regresión de seguridad y es específico para los paquetes docker producidos por Red Hat. El problema original, CVE-2016-9962, podría permitir a un proceso dentro del contenedor comprometer un proceso que ingresa al espacio de nombres del contenedor y ejecutar código arbitrario fuera del contenedor. Esto podría comprometer el host del contenedor u otros contenedores que se ejecutan en el mismo host del contenedor. Este problema solo afecta a una versión única de Docker, 1.13.1-108.git4ef4b30, incluida en Red Hat Enterprise Linux 7. Las versiones anteriores y posteriores no están afectadas

This issue could allow a malicious or compromised container to compromise the container host and other containers running on the same host.
