The version of containerd installed on the remote host is prior to 1.4.6-8. It is, therefore, affected by a vulnerability as referenced in the ALAS2ECS-2023-024 advisory.
Note that Nessus has not tested for this issue but has instead relied only on the applicationโs self-reported version number.

"The version of containerd installed on the remote host is prior to 1.4.6-8. It is, therefore, affected by a
vulnerability as referenced in the ALAS2ECS-2023-024 advisory.
- containerd is a container runtime available as a daemon for Linux and Windows. A bug was found in
containerd prior to versions 1.6.1, 1.5.10, and 1.14.12 where containers launched through containerd's CRI
implementation on Linux with a specially-crafted image configuration could gain access to read-only copies
of arbitrary files and directories on the host. This may bypass any policy-based enforcement on container
setup (including a Kubernetes Pod Security Policy) and expose potentially sensitive information.
Kubernetes and crictl can both be configured to use containerd's CRI implementation. This bug has been
fixed in containerd 1.6.1, 1.5.10, and 1.4.12. Users should update to these versions to resolve the issue.
