CVE-2011-1784 is a vulnerability of currently unknown severity. The pidfile_write function in core/pidfile.c in keepalived 1.2.2 and earlier uses 0666 permissions for the (1) keepalived.pid, (2) checkers.pid, and (3) vrrp.pid files in /var/run/, which allows local users to kill arbitrary processes by writing a PID to one of these files.. EPSS estimates a 0.37% chance of exploitation in the next 30 days.
