The Apache Group takes a very active stance in eliminating security
problems and denial of service attacks against the Apache web server.
Lists of security problems in released versions of the Apache HTTP
Server are available from ApacheWeek:
We strongly encourage folks to report such problems to our private
security mailing list first, before disclosing them in a public forum.
We cannot accept regular bug reports or other queries at
this address, we ask that you use our bug
reporting page for those. All mail sent to this
address that does not relate to security problems in the Apache source
code will be ignored.
The mailing address is:
security@apache.org
Note that all networked servers are subject to denial of service
attacks, and we cannot promise magic workarounds to generic problems
(such as a client streaming lots of data to your server, or re-requesting
the same URL repeatedly). In general our philosophy is to avoid any
attacks which can cause the server to consume resources in a non-linear
relationship to the size of inputs.
