Vulnerabilidad en runc (CVE-2019-5736)
Gravedad CVSS v3.1:
ALTA
Tipo:
CWE-78
Neutralización incorrecta de elementos especiales usados en un comando de sistema operativo (Inyección de comando de sistema operativo)
Fecha de publicación:

Descripción
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.
