CVE-2019-14317

wolfSSL and wolfCrypt 4.1.0 and earlier formerly known as CyaSSL generate biased DSA nonces. This allows a remote attacker to compute the long term private key from several hundred DSA signatures via a lattice attack. The issue occurs because dsa.c fixes two bits of the generated nonces...

CVE-2019-14317

Summary of the vulnerability (CVE-2019-14317) : In wolfSSL/wolfCrypt up to version 4.1.0, DSA nonces are biased because dsa.c fixes two bits of the nonces. This bias makes it possible for a remote attacker to recover the long-term DSA private key after observing several hundred signatures, via a ...
