Descriptions

Docker Engine before 18.09 allows attackers to cause a denial of service (dockerd memory consumption) via a large integer in a --cpuset-mems or --cpuset-cpus value, related to daemon/daemon_unix.go, pkg/parsers/parsers.go, and pkg/sysinfo/sysinfo.go.

Docker Engine, en versiones anteriores a la 18.09, permite que los atacantes provoquen una denegación de servicio (consumo de la memoria dockerd) mediante un entero grande en los valores --cpuset-mems o --cpuset-cpus. Esto está relacionado con daemon/daemon_unix.go, pkg/parsers/parsers.go y pkg/sysinfo/sysinfo.go.

Docker is an open-source engine that automates the deployment of any application as a lightweight, portable, self-sufficient container that runs virtually anywhere. Issues addressed include a memory exhaustion vulnerability.
