[3.5] openldap: Privilege escalation via PID file manipulation (CVE-2017-14159)
slapd in OpenLDAP 2.4.45 and earlier creates a 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 PID file modification before a root script
executes a “kill `cat /pathname`” command, as demonstrated by
openldap-initscript.
