...e who contributed to this release. Security ======== * ssh(1), sshd(8), ssh-agent(1): add protection for private keys at rest in RAM against speculation and memory sidechannel attacks like Spectre, Meltdown and Rambleed. This release encrypts private keys when they are not in use with a symmetic key that is derived from a relatively large "prekey" consisting of random data (currently 16KB). Attackers must recover the entire prekey before they are able to decrypt the protected private keys, but the current generation of attacks have bit error rates that render this u...
