Insecure Permissions in keepalived.pid, checkers.pid, and vrrp.pid Files Allow Process Killing
CVE-2011-1784 · LOW Severity
AV:L/AC:L/AU:N/C:N/I:P/A:P
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.
