Описание
A Bleichenbacher type side-channel based padding oracle attack was found in the way nettle handles endian conversion of RSA decrypted PKCS#1 v1.5 data. An attacker who is able to run a process on the same physical core as the victim process, could use this flaw extract plaintext or in some cases downgrade any TLS connections to a vulnerable server.

The upstream correction also makes a new public function that packages using
nettle should use. This means that fixing this CVE is a pre-requisite for
fixing other CVEs like CVE-2018-16868.
