From: tmark@isc.org
Subject: Using relative paths for for lease or config files can crash dhclient
Date: Fri, 05 Jan 2018 12:30:34 +0000

Not all systems support NULL for the second parameter to realpath(), yet in both dhclient.c and dhcpd.c, this is precisely what we do causing segfaults when using relative lease or config file arguments. Found this under NetBSD 6.2_BETA2 (GENERIC) i386, gcc version 4.5.3.
