What is CVE-2018-20699?

A vulnerability in Docker Engine allows attackers to exploit large integer values for the --cpuset-mems or --cpuset-cpus parameters. This can lead to excessive memory consumption by the dockerd process, resulting in a denial of service. The affected code components related to this vulnerability include daemon/daemon_unix.go, pkg/parsers/parsers.go, and pkg/sysinfo/sysinfo.go. Users of Docker Engine versions before 18.09 should apply necessary updates to mitigate this risk.
