NewCVE-2024-25621 Â (opens in a new tab)How to fix?
Upgrade github.com/containerd/containerd/v2/cmd/containerd/server to version 2.0.7, 2.1.5, 2.2.0 or higher.
Overview
Affected versions of this package are vulnerable to Incorrect Execution-Assigned Permissions when initialising host directories with 711 and 755 permissions instead of 700. An attacker can gain unauthorized access to sensitive data and potentially escalate privileges by accessing directories with insufficiently restrictive permissions. This is only exploitable if a local user has access to the host system where the affected directories are present.
Workaround
This vulnerability can be mitigated by manually setting the permissions of the affected directories (/var/lib/containerd, /run/containerd/io.containerd.grpc.v1.cri, /run/containerd/io.containerd.sandbox.controller.v1.shim, temp in the daemon configuration) to 700 or by running the process in rootless mode.
