FreeBSD : FreeBSD -- devfs rules not applied by default for jails (6b6ca5b6-6007-11e6-a6c3-14dae9d210b8)
Medium Nessus Plugin ID 92899
SynopsisThe remote FreeBSD host is missing a security-related update.
DescriptionThe default devfs rulesets are not loaded on boot, even when jails are used. Device nodes will be created in the jail with their normal default access permissions, while most of them should be hidden and inaccessible. Impact : Jailed processes can get access to restricted resources on the host system. For jailed processes running with superuser privileges this implies access to all devices on the system.
This level of access could lead to information leakage and privilege escalation.
SolutionUpdate the affected package.
