| CVE-2002-20001 | — | < 1.1.1m-4.1 | 1.1.1m-4.1 | Nov 11, 2021 | 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 D(HE)at or D(HE)ater attack. The client needs ver | ||
