EulerOS 2.0 SP12 : docker-runc (EulerOS-SA-2024-1853)
medium Nessus Plugin ID 201138
Synopsis
The remote EulerOS host is missing a security update.Description
According to the versions of the docker-runc package installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :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`.(CVE-2023-25809)
Tenable has extracted the preceding description block directly from the EulerOS docker-runc security advisory.
Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.
