CVE-2020-12413

A flaw was found in Mozilla nss. A raccoon attack exploits a flaw in the TLS specification which can lead to an attacker being able to compute the pre-master secret in connections which have used a Diffie-HellmanDH based ciphersuite. In such a case this would result in the attacker being able to...
