CVE-2022-31030: Debian Linux

Medium severity, CVSS 5.5. EPSS: 0.4% chance of exploitation in the next 30 days.

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.

Affected products

• Debian Debian Linux: version 11.0 only
• Fedoraproject Fedora: version 35 only; version 36 only
• Linuxfoundation Containerd: before 1.5.13 (fixed in 1.5.13); from 1.6.0, before 1.6.6 (fixed in 1.6.6)
