Replacing the cache-based side channel with our port contention side channel "SMoTher" allows us to leak secrets *during* speculative execution (through execution timing), not afterwards (through cache contention). Get more secret data, leverage easier gadgets!https://twitter.com/ICepfl/status/1108277453762543616 …

I'm glad to present our LTE Layer Two Analysis with the title "Breaking LTE on Layer Two". Our work reveals two passive attacks and the active aLTEr attack, that allows redirecting of DNS requests to a malicious DNS server.

They figured out mail clients which don't properly check for decryption errors and also follow links in HTML mails. So the vulnerability is in the mail clients and not in the protocols. In fact OpenPGP is immune if used correctly while S/MIME has no deployed mitigation.
