Descriptions

Botan before 1.10.13 and 1.11.x before 1.11.29 do not use a constant-time algorithm to perform a modular inverse on the signature nonce k, which might allow remote attackers to obtain ECDSA secret keys via a timing side-channel attack.

Botan en versiones anteriores a 1.10.13 y 1.11.x en versiones anteriores a 1.11.29 no utiliza un algoritmo de tiempo constante para realizar un inverso modular en la firma k nonce, lo que podría permitir a atacantes remotos obtener claves secretas ECDSA a través de un ataque de sincronización de canal lateral.
