CVE-2013-0157 low priority: Debian including 1 source packages (util-linux), 5 status rows across 5 suites (bookworm, bullseye, forky, sid, trixie): resolved 5.
(a) mount and (b) umount in util-linux 2.14.1, 2.17.2, and probably other versions allow local users to determine the existence of restricted directories by (1) using the --guess-fstype command-line option or (2) attempting to mount a non-existent device, which generates different error messages depending on whether the directory exists.
