Descriptions
runc through 1.0-rc6, as used in Docker before 18.09.2 and other products, allows attackers to overwrite the host runc binary (and consequently obtain host root access) by leveraging the ability to execute a command as root within one of these types of containers: (1) a new container with an attacker-controlled image, or (2) an existing container, to which the attacker previously had write access, that can be attached with docker exec. This occurs because of file-descriptor mishandling, related to /proc/self/exe.
runc, hasta la versión 1.0-rc6, tal y como se emplea en Docker, en versiones anteriores a la 18.09.2 y otros productos, permite que los atacantes sobrescriban el binario del host runc (y, así, obtengan acceso root al host) aprovechando la capacidad para ejecutar un comando como root con uno de estos tipos de contenedores: (1) un nuevo contenedor con una imagen controlada por el atacante o (2) un contenedor existente, para el cual el atacante contaba previamente con acceso de escritura, que puede adjuntarse con docker exec. Esto ocurre debido a la gestión incorrecta del descriptor de archivos; esto está relacionado con /proc/self/exe.
A flaw was found in the way runc handled system file descriptors when running containers. A malicious container could use this flaw to overwrite contents of the runc binary and consequently run arbitrary commands on the container host system.
