description: |
    A DoS vulnerability in the crypto/elliptic implementations of the P-521 and
    P-384 elliptic curves may let an attacker craft inputs that consume
    excessive amounts of CPU.

    These inputs might be delivered via TLS handshakes, X.509 certificates, JWT
    tokens, ECDH shares or ECDSA signatures. In some cases, if an ECDH private
    key is reused more than once, the attack can also lead to key recovery.
