CVE-2017-14102: Mimedefang

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

MIMEDefang 2.80 and earlier creates 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 the init-script.in and mimedefang-init.in scripts.
