JSON

main.c in Tinyproxy 1.8.4 and earlier creates a
/run/tinyproxy/tinyproxy.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 tinyproxy.pid modification
before a root script executes a “kill cat /run/tinyproxy/tinyproxy.pid”
command.
