  script_set_attribute(attribute:"description", value:
"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.runc 1.1.13 and
    earlier, as well as 1.2.0-rc2 and earlier, can be tricked into creating empty files or directories in
    arbitrary locations in the host filesystem by sharing a volume between two containers and exploiting a
    race with `os.MkdirAll`.While this could be used to create empty files, existing files would not be
    truncated.An attacker must have the ability to start containers using some kind of custom volume
    configuration.Containers using user namespaces are still affected, but the scope of places an attacker can
    create inodes can be significantly reduced.Sufficiently strict LSM policies (SELinux/Apparmor) can also in
    principle block this attack -- we suspect the industry standard SELinux policy may restrict this attack's
    scope but the exact scope of protection hasn't been analysed.This is exploitable using runc directly as
    well as through Docker and Kubernetes.The issue is fixed in runc v1.1.14 and v1.2.0-rc3. Some workarounds
    are available.Using user namespaces restricts this attack fairly significantly such that the attacker can
    only create inodes in directories that the remapped root user/group has write access to.Unless the root
    user is remapped to an actual user on the host (such as with rootless containers that don't use
    `/etc/sub[ug]id`), this in practice means that an attacker would only be able to create inodes in world-
    writable directories.A strict enough SELinux or AppArmor policy could in principle also restrict the scope
    if a specific label is applied to the runc runtime, though neither the extent to which the standard
    existing policies block this attack nor what exact policies are needed to sufficiently restrict this
    attack have been thoroughly tested.(CVE-2024-45310)

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.");
