memcached (1.4.33-1+deb9u1) stretch-security; urgency=high

  * memcached is now configured to disable its UDP port by default, to
    prevent its use as a DDoS amplifier. To re-enable UDP service, add
    '-U 11211' to /etc/memcached.conf and restart the memcached service.

memcached (1.4.20-1) unstable; urgency=medium

    Starting with this release, a system user "memcache" will be created.
    If you upgrade from an earlier release, you can change your configuration to
    use it in your /etc/memcached*.conf (see the -u option).
