Does this matter?
EPSS puts the probability of exploitation in the next 30 days at 82.1%, higher than 100% of all known CVEs. Patch or mitigate before the next change window.
Description
The SSLv2 protocol, as used in OpenSSL before 1.0.1s and 1.0.2 before 1.0.2g and other products, requires a server to send a ServerVerify message before establishing that a client possesses certain plaintext RSA data, which makes it easier for remote attackers to decrypt TLS ciphertext data by leveraging a Bleichenbacher RSA padding oracle, aka a "DROWN" attack.
