Описание
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.

Отчет
This issue did not affect the versions of podman as shipped with Red Hat Enterprise Linux 8 as they did not include support for the copy function. This issue did not affect the versions of podman as shipped in OpenShift Container Platform 3.11 and 4.1 as they did not include support for the copy function. The version of podman shipped in OpenShift Container Platform 4.2 was superseded by the version delivered Red Hat Enterprise Linux 8.
