Helix RealServer Remote Integer Handling DoS



The remote host is vulnerable to a Denial of Service (DoS) attack.


RealServer versions and prior as well as and prior are vulnerable to a remote Denial of Service (DoS) attack when they are presented with an invalid (negative) integer for the Content-Length field. An attacker exploiting this flaw would need to be able to connect to the RealServer (default port 554) and issue a malformed request. A successful attack would consume large amounts of memory on the RealServer, eventually ending in the unavailability of the server.


Upgrade to version, or higher.
