"According to its banner, the version of Apache 2.4.x running on the
remote host is version 2.4.6. It is, therefore, affected by a flaw in
the mod_cache module involving a NULL pointer dereference. An attacker
may be able to specially craft a request designed to cause a denial of
service.

Note that Nessus has not tested for this issue but has instead relied
only on the application's self-reported version number.");
