ArchLinux: 202009-11: podman: information disclosure
Summary
A flaw was discovered in Podman before upstream version 2.0.5. When using the deprecated Varlink API or the Docker-compatible REST API, if multiple containers are created in a short duration, the environment variables from the first containers will get leaked into subsequent containers. An attacker who has control over those subsequent containers may get access to secrets shared with previous containersthrough environment variables.
Resolution
Upgrade to 2.1.0-1.
# pacman -Syu "podman>=2.1.0-1"
The problem has been fixed upstream in version 2.1.0.
