Updated docker-containerd packages fix security vulnerability

Publication date: 06 Mar 2022
Type: security
Affected Mageia releases : 8
CVE: CVE-2022-23648


A bug was found in containerd where containers launched through containerd’s
CRI implementation 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. (CVE-2022-23648)
