NVD Description

Note: Versions mentioned in the description apply only to the upstream keepalived package and not the keepalived package as distributed by Debian. See How to fix? for Debian:unstable relevant fixed versions and status.

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.
