| 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. |
