Synopsis

The remote Amazon Linux AMI host is missing a security update.

Description

A vulnerability was discovered in runc, which is used by Docker to run containers. runc did not prevent container processes from modifying the runc binary via /proc/self/exe. A malicious container could replace the runc binary, resulting in container escape and privilege escalation. This was fixed by creating a per-container copy of runc.(CVE-2019-5736)
