Category:	Huawei EulerOS Local Security Checks
Title:	Huawei EulerOS: Security Advisory for docker-runc (EulerOS-SA-2024-1853)
Summary:	The remote host is missing an update for the Huawei EulerOS 'docker-runc' package(s) announced via the EulerOS-SA-2024-1853 advisory.
Description:	Summary: The remote host is missing an update for the Huawei EulerOS 'docker-runc' package(s) announced via the EulerOS-SA-2024-1853 advisory. Vulnerability Insight: 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.., `(dockerpodmannerdctl) 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 (`(dockerpodmannerdctl) 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) Affected Software/OS: 'docker-runc' package(s) on Huawei EulerOS V2.0SP12. Solution: Please install the updated package(s). CVSS Score: 4.3 CVSS Vector: AV:L/AC:L/Au:S/C:P/I:P/A:P
