Description
From CVE.org
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.
Statement
This issue affects the versions of docker as shipped with Red Hat Enterprise Linux 7, however if docker is accessible only by root or highly privileged users, as it is by default, a low-privileged attacker will not be able to trigger the flaw.
Common Vulnerability Scoring System (CVSS) Score Details
Info alert:Important note
CVSS scores for open source components depend on vendor-specific factors (e.g. version or build chain). Therefore, Red Hat's score and impact rating can be different from NVD and other vendors. Red Hat remains the authoritative CVE Naming Authority (CNA) source for its products and services (see Red Hat classifications).
