"value" : "In Docker before versions 9.03.15, 20.10.3 there is a vulnerability involving the --userns-remap option in which access to remapped root allows privilege escalation to real root. When using \"--userns-remap\", if the root user in the remapped namespace has access to the host filesystem they can modify files under \"/var/lib/docker/<remapping>\" that cause writing files with extended privileges. Versions 20.10.3 and 19.03.15 contain patches that prevent privilege escalation from remapped user."

"value" : "En Docker versiones anteriores a 9.03.15, 20.10.3, se presenta una vulnerabilidad que involucra la opci\u00f3n --userns-remap en la que un acceso a una root reasignada permite una escalada de privilegios a la root actual. Cuando se usa \"--userns-remap\", si el usuario root en el espacio de nombres reasignado tiene acceso al sistema de archivos del host, puede modificar archivos en \"/var/lib/docker/(remapping)\" que causa la escritura de archivos con privilegios extendidos. Las versiones 20.10.3 y 19.03.15 contienen parches que evitan una escalada de privilegios del usuario reasignado"
