CVE-2017-14609: Kannel

High severity, CVSS 7.8. EPSS: 0.4% chance of exploitation in the next 30 days.

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.

Affected products

• Kannel Kannel: up to and including 1.5.0
