Erick Dantas Rotole and Henrik Nordstrom discovered that squid could end
up in an endless loop when exhausted of available external ACL helpers.
Remote users with access to squid could cause CPU starvation, possibly
leading to a denial of service. This does not affect a default Ubuntu
installation, since external ACL helpers must be configured and used.
