Vulnerability Description
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 very little CPU resources and network bandwidth. The attack may be more disruptive in cases where a client 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.

Diffie-Hellman Key Agreement Protocol 资源管理错误漏洞
Source: CNNVD (China National Vulnerability Database)
Vulnerability Description
Diffie-Hellman Key Agreement Protocol是一种密钥协商协议。它最初在 Diffie 和 Hellman 关于公钥密码学的开创性论文中有所描述。该密钥协商协议允许 Alice 和 Bob 交换公钥值，并根据这些值和他们自己对应的私钥的知识，安全地计算共享密钥K，从而实现进一步的安全通信。仅知道交换的公钥值，窃听者无法计算共享密钥。 Diffie-Hellman Key Agreement Protocol 存在资源管理错误漏洞，远程攻击者可以发送实际上不是公钥的任意数字，并
