Description
runc is a CLI tool for spawning and running containers according to the OCI specification. In affected versions it was found that rootless runc makes 'sys/fs/cgroup' writable in following conditons: 1. when runc is executed inside the user namespace, and the 'config.json' does not specify the cgroup namespace to be unshared (e.g.., '(docker|podman|nerdctl) run --cgroupns=host', with Rootless Docker/Podman/nerdctl) or 2. when runc is executed outside the user namespace, and '/sys' is mounted with 'rbind, ro' (e.g., 'runc spec --rootless'; this condition is very rare). A container may gain the write access to user-owned cgroup hierarchy '/sys/fs/cgroup/user.slice/...' on the host . Other users's cgroup hierarchies are not affected. Users are advised to upgrade to version 1.1.5. Users unable to upgrade may unshare the cgroup namespace ('(docker|podman|nerdctl) run --cgroupns=private)'. This is the default behavior of Docker/Podman/nerdctl on cgroup v2 hosts. or add '/sys/fs/cgroup' to 'maskedPaths'.
