- Summary
- containerd CRI plugin: Host memory exhaustion through ExecSync
- Details
-
Impact
A bug was found in containerd's CRI implementation where programs inside a container can cause the containerd daemon to consume memory without bound during invocation of the
ExecSyncAPI. 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;ExecSyncmay be used when running probes or when executing processes via an "exec" facility.Patches
This bug has been fixed in containerd 1.6.6 and 1.5.13. Users should update to these versions to resolve the issue.
Workarounds
Ensure that only trusted images and commands are used.
