EulerOS 2.0 SP13 : docker-runc (EulerOS-SA-2026-4133)
medium Nessus Plugin ID 364750
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 versions prior to 1.3.6, 1.4.0-rc.1, 1.4.0-rc.12, 1.5.0-rc.1, and 1.5.0-rc.1, when setting up the container rootfs, setupPtmx and setupDevSymlinks call os.Remove and os.Symlink with a filepath.Join string which allow an image with /dev as a symlink to trick runc into deleting files called ptmx on the host or creating a hardcoded set of symlinks with specific names and targets in an arbitrary pre-existing host directory.
This issue is not exploitable under Docker, because Docker creates a top-level read-only layer that masks any malicious /dev symlink present in the container image - unlike some other Linux container tooling, whose higher-level runtimes built on runc remain exposed to exploitation via a malicious image. This issue has been fixed in versions 1.3.6, 1.4.3 and 1.5.0.(CVE-2026-41579)
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.
