Jann Horn discovered that microprocessors utilizing speculative
execution and branch prediction may allow unauthorized memory
reads via sidechannel attacks. This flaw is known as Spectre. A
local attacker could use this to expose sensitive information,
including kernel memory. This update provides mitigations for the
i386 (CVE-2017-5753 only), amd64, ppc64el, and s390x architectures.
(CVE-2017-5715, CVE-2017-5753)
USN-3522-1 mitigated CVE-2017-5754 (Meltdown) for the amd64
architecture in Ubuntu 16.04 LTS. This update provides the
corresponding mitigations for the ppc64el architecture. Original
