This issue is different from CVE-2002-20001 because it is based on an observation about exponent size, rather than an observation about numbers that are not public keys. The specific situations in which calculation expense would constitute a server-side vulnerability depend on the protocol (e.g., TLS, SSH, or IKE) and the DHE implementation details. In general, there might be an availability concern because of server-side resource consumption from DHE modular-exponentiation calculations. Finally, it is possible for an attacker to exploit this vulnerability and CVE-2002-20001 together.</p> <p>The Diffie-Hellman Key Agreement Protocol allows use of long exponents that arguably make certain calculations unnecessarily expensive, because the 1996 van Oorschot and Wiener paper found that &#34;(appropriately) short exponents&#34; can be used when there are adequate subgroup constraints, and these short exponents can lead to less expensive calculations than for long exponents.

An attacker may cause asymmetric resource consumption with any common client application which uses a DHE implementation that applies short exponents. The attack may be more disruptive in cases where a client sends arbitrary numbers that are actually not DH public keys (aka the D(HE)ater attack) or can require a server to select its largest supported key size. The basic attack scenario is that the client must claim that it can only communicate with DHE, and the server must be configured to allow DHE. This can affect TLS, SSH, and IKE.</p> <p>Using long exponents in the Diffie-Hellman Key Agreement Protocol allows remote attackers (from the client side) to trigger unnecessarily expensive server-side DHE modular-exponentiation calculations.
