The remote web server is affected by a denial of service
vulnerability.

to the 'Host:' field of an HTTP request.

An attacker may use this flaw to either completely prevent this host
from serving web pages to the world, or to make it die by crashing
several threads of the web server until the complete exhaustion of
this host memory
