Описание
A flaw was found in crun. When the container configuration does not give /dev a dedicated mount, terminal setup can redirect /dev/console onto an attacker-controlled path, including via the read-only-rootfs bind-mount fallback. Affected versions are crun 1.29.1 and earlier. Default configurations that mount a fresh /dev are not exposed. No fixed release is available yet.
Отчет
Exploitation requires an OCI configuration that does not mount /dev, plus a malicious image. Supported Red Hat container tooling mounts /dev by default. Red Hat products are not affected in supported configurations.
Меры по смягчению последствий
Always mount /dev (Podman/crun default). Do not run untrusted images with a /dev-less config.
