Quite probably.
negative_ttl forces Squid to cache and provide ALL clients with the 4xx
or 5xx error page for a certain length of time. Even if it was only a
temporary issue due to a single client request failure. It's a manually
added DoS vulnerability to every Squid which uses it.
It's rarely useful nowdays even for its original purpose of reducing 404
flooding of backend servers.
