Summary
Details

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.

Severity
