This issue was opened to check on the possible need for Meltdown and Spectre attack mitigation. These attack vectors basically allow known memory locations to be read, possibly exposing sensitive data. The one issue that was brought up would be keeping private keys unencrypted in memory for too long and exposing them to this attack. However these vulnerabilities are still relatively new and the mitigations for them are not finalized. At the time of this writing no specific changes have been outlined or put in place.
