Amazon Linux 2 : containerd (ALASNITRO-ENCLAVES-2022-020)

medium Nessus Plugin ID 162012

Language:

Synopsis

The remote Amazon Linux 2 host is missing a security update.

Description

The version of containerd installed on the remote host is prior to 1.4.13-3. It is, therefore, affected by a vulnerability as referenced in the ALAS2NITRO-ENCLAVES-2022-020 advisory.

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 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. (CVE-2022-31030)

Tenable has extracted the preceding description block directly from the tested product security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Run 'yum update containerd' to update your system.
