CVE-2018-3639 (SSB)

Multiple researchers have discovered that Speculative Store Bypass
(SSB), a feature implemented in many processors, could be used to
read sensitive information from another context. In particular,
code in a software sandbox may be able to read sensitive
information from outside the sandbox. This issue is also known as
Spectre variant 4.

This update fixes bugs in the mitigations for SSB for AMD
processors.
