CVE-2002-20001: Uncontrolled Resource Consumption

The Diffie-Hellman Key Agreement Protocol allows remote attackers from the client side to send arbitrary numbers that are actually not public keys, and trigger expensive server-side DHE modular-exponentiation calculations, aka a DHEat or DHEater attack. The client needs very little CPU resources...
