Who is Vulnerable?
Vulnerability Description A denial of service vulnerability has been reported in all web servers. The vulnerability is due to the server's inability to handle multiple incoming requests within a short period of time. Remote attackers may exploit this issue by rapidly sending a large number of HTTP requests to the server. The attack may be initiated from one or more sources (DDoS). Successful exploitation may cause the server to crash, resulting in a denial of service condition.
