Last modified

CVE-2017-14609 is a vulnerability of currently unknown severity. 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.. EPSS estimates a 0.41% chance of exploitation in the next 30 days.
