Summary
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) and amd64 architectures.
