    Published: 23 Aug 2017Last Modified: 8 Jul 2026

    Summary:

    Details: Nagios Core before 4.3.3 creates a nagios.lock 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 nagios.lock modification before a root script executes a "kill `cat /pathname/nagios.lock`" command.
