'podman cp' will resolve a carefully crafted symlink in host-filesystem space, yielding unexpected results when cp'ing from container to host. An attacker could create a container image containing particular symlinks that, when copied by a victim user to the host filesystem, may overwrite existing files with others from the host.

Upstream Issue: https://github.com/containers/libpod/issues/3829

A path traversal vulnerability has been discovered in podman before version 1.4.0 in the way it handles symlinks inside containers. An attacker who has compromised an existing container can cause arbitrary files on the host filesystem to be read/written when an administrator tries to copy a file from/to the container.

It has been discovered that podman before version 0.6.1 does not drop capabilities when executing a container as a non-root user. This results in unnecessary privileges being granted to the container.
