NVD Description

Note: Versions mentioned in the description apply only to the upstream falco package and not the falco package as distributed by Chainguard. See How to fix? for Chainguard relevant fixed versions and status.

A flaw was found in Podman. In a Containerfile or Podman, data written to RUN --mount=type=bind mounts during the podman build is not discarded. This issue can lead to files created within the container appearing in the temporary build context directory on the host, leaving the created files accessible.
