CVE-2018-11070
RSA BSAFE Crypto-J versions prior to 6.2.4 and RSA BSAFE SSL-J versions prior to 6.2.4 contain a Covert Timing Channel vulnerability during PKCS #1 unpadding operations, also known as a Bleichenbacher attack.
Does this matter?
Lower severity and a low EPSS score (1.66%). Track it; it rarely justifies an emergency change on its own.
