CVE-2017-12847 is a vulnerability of currently unknown severity. 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.. EPSS estimates a 0.79% chance of exploitation in the next 30 days.
