[3.5] coreutils: privilege escalation via recursive dereferences (CVE-2017-18018)
In GNU Coreutils through 8.29, chown-core.c in chown and chgrp does not
prevent replacement of a plain file with
a symlink during use of the POSIX “-R -L” options, which allows local users to modify the ownership of
arbitrary files by leveraging a race condition.
