Upgrade Ubuntu:22.04 node-tar-fs to version 2.1.1-6ubuntu0.22.04.1~esm1 or higher.
NVD Description
Note: Versions mentioned in the description apply only to the upstream node-tar-fs package and not the node-tar-fs package as distributed by Ubuntu.
See How to fix? for Ubuntu:22.04 relevant fixed versions and status.
tar-fs provides filesystem bindings for tar-stream. Versions prior to 3.0.9, 2.1.3, and 1.16.5 have an issue where an extract can write outside the specified dir with a specific tarball. This has been patched in versions 3.0.9, 2.1.3, and 1.16.5. As a workaround, use the ignore option to ignore non files/directories.
