Ubuntu 20.04 LTS / 21.10 : containerd regression (USN-5311-2)

high Nessus Plugin ID 161245


The remote Ubuntu host is missing a security update.


The remote Ubuntu 20.04 LTS / 21.10 host has packages installed that are affected by a vulnerability as referenced in the USN-5311-2 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.

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


Update the affected containerd and / or golang-github-containerd-containerd-dev packages.
