Centos 7 : runc

high Nessus Plugin ID 130262

Language:

Synopsis

The remote CentOS host is missing one or more security updates.

Description

An update for runc is now available for CentOS 7 Extras.

The runC tool is a lightweight, portable implementation of the Open Container Format (OCF) that provides container runtime.

A flaw was found in the way runc handled system file descriptors when running containers. A malicious container could use this flaw to overwrite contents of the runc binary and consequently run arbitrary commands on the container host system. (CVE-2019-5736)

Solution

Update the affected runc, docker, and / or docker-ce packages.
