CVE-2014-0076
The Montgomery ladder implementation in OpenSSL through 1.0.0l does not ensure that certain swap operations have a constant-time behavior, which makes it easier for local users to obtain ECDSA nonces via a FLUSH+RELOAD cache side-channel attack.

Does this matter?
Lower severity and a low EPSS score (0.84%). Track it; it rarely justifies an emergency change on its own.
