UBUNTU-CVE-2024-41996

Validating the order of the public keys in the Diffie-Hellman Key Agreement Protocol, when an approved safe prime is used, allows remote attackers from the client side to trigger unnecessarily expensive server-side DHE modular-exponentiation calculations. The client may cause asymmetric resource...

Diffie-Hellman 安全漏洞

Diffie-Hellman is a key negotiation protocol open-sourced by Diffie-Hellman. This key negotiation protocol allows Alice and Bob to exchange public key values and securely compute the shared key K based on knowledge of these values and their own corresponding private keys, enabling further secure...
