Upgrade Debian:unstable tinyproxy to version 1.10.0-1 or higher.
NVD Description
Note: Versions mentioned in the description apply only to the upstream tinyproxy package and not the tinyproxy package as distributed by Debian.
See How to fix? for Debian:unstable relevant fixed versions and status.
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.
