Red Hat: CVE-2019-18466: CVE-2019-18466 podman: resolving symlink in host filesystem leads to unexpected results of copy operation (Multiple Advisories)

An issue was discovered in Podman in libpod before 1.6.0. It resolves a symlink in the host context during a copy operation from the container to the host, because an undesired glob operation occurs. 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.
