+	<h1>Problem Description:</h1>
+	<p>A number of issues relating to speculative execution
+	were found last year and publicly announced January 3rd.
+	Two of these, known as Meltdown and Spectre V2, are addressed
+	here.</p>
+	<p>CVE-2017-5754 (Meltdown) - ------------------------</p>
+	<p>This issue relies on an affected CPU speculatively
+	executing instructions beyond a faulting instruction. When
+	this happens, changes to architectural state are not
+	committed, but observable changes may be left in micro-
+	architectural state (for example, cache). This may be used
+	to infer privileged data.</p>
+	<p>CVE-2017-5715 (Spectre V2) - --------------------------</p>
+	<p>Spectre V2 uses branch target injection to speculatively
+	execute kernel code at an address under the control of an
+	attacker.</p>
+	<h1>Impact:</h1>
+	<p>An attacker may be able to read secret data from the
+	kernel or from a process when executing untrusted code (for
+	example, in a web browser).</p>
