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-Hellman(DH) based ciphersuite. In such a case this would result in the attacker being able to eavesdrop on all encrypted communications sent over that TLS connection. The highest threat from this vulnerability is to data confidentiality.

Mitigation

Any risk involving the ECDHE key reuse on the nss server can be mitigated by setting the SSL_REUSE_SERVER_ECDHE_KEY socket option to PR_FALSE.
