CVE-2017-14609 Information

Description

The server daemons in Kannel 1.5.0 and earlier create a 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 PID file modification before a root script executes a \kill cat /pathname\ command as demonstrated by bearerbox.
