"According to the versions of the docker-engine package installed, the EulerOS installation on the remote host is
affected by the following vulnerabilities :

  - containerd is an open source container runtime. A bug was found in the containerd's CRI implementation
    where programs inside a container can cause the containerd daemon to consume memory without bound during
    invocation of the `ExecSync` API. This can cause containerd to consume all available memory on the
    computer, denying service to other legitimate workloads. Kubernetes and crictl can both be configured to
    use containerd's CRI implementation; `ExecSync` may be used when running probes or when executing
    processes via an 'exec' facility. This bug has been fixed in containerd 1.6.6 and 1.5.13. Users should
    update to these versions to resolve the issue. Users unable to upgrade should ensure that only trusted
    images and commands are used. (CVE-2022-31030)

Note that Tenable Network Security has extracted the preceding description block directly from the EulerOS security
advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional
issues.");
