Fix(es): * An industry-wide issue was found in the way many modern
microprocessor designs have implemented speculative execution of instructions (a
commonly used performance optimization). There are three primary variants of the
issue which differ in the way the speculative execution can be exploited.
Variant CVE-2017-5715 triggers the speculative execution by utilizing branch
target injection. It relies on the presence of a precisely-defined instruction
sequence in the privileged code as well as the fact that memory accesses may
cause allocation into the microprocessor's data cache even for speculatively
executed instructions that never actually commit (retire). As a result, an
unprivileged attacker could use this flaw to cross the syscall and guest/host
boundaries and read privileged memory by conducting targeted cache side-channel
attacks. (CVE-2017-5715) Note: This is the microcode counterpart of the
CVE-2017-5715 kernel mitigation. Red Hat would like to thank Google Project Zero
for reporting this issue.");
