+ <p>The signing function in crypto/ecdsa/ecdsa_ossl.c in certain OpenSSL
+ versions and forks is vulnerable to timing attacks when signing with the
+ standardized elliptic curve P-256 despite featuring constant-time curve
+ operations and modular inversion. A software defect omits setting the
+ BN_FLG_CONSTTIME flag for nonces, failing to take a secure code path in
+ the BN_mod_inverse method and therefore resulting in a cache-timing attack
+ vulnerability.<br/>
+ A malicious user with local access can recover ECDSA P-256 private keys.</p>
