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.
