CVE-2017-14681

The daemon in P3Scan 3.0_rc1 and earlier creates a p3scan.pid file after
dropping privileges to a non-root account, which might allow local users to
kill arbitrary processes by leveraging access to this non-root account for
p3scan.pid modification before a root script executes a “kill cat /pathname/p3scan.pid” command, as demonstrated by etc/init.d/p3scan.
