Description
Problem Description: The length field of the option header does not count the size of the option header itself. This causes a problem when the length is zero, the count is then incremented by zero, which causes an infinite loop. In addition there are pointer/offset mistakes in the handling of IPv4 options. Impact: A remote attacker who is able to send an arbitrary packet, could cause the remote target machine to crash.
