+# Summary
+
+Project zero has recently announced some new attacks that have received a
+lot of attention:
+https://googleprojectzero.blogspot.ca/2018/01/reading-privileged-memory-with-side.html.
+
+The risk from these attacks to systems running Node.js resides in the
+systems in which your Node.js applications run, as opposed to the
+Node.js runtime itself. The trust model for Node.js assumes you are
+running trusted code and does not provide any separation between code
+running within the runtime itself. Therefore, untrusted code that
+would be necessary to execute these attacks in Node.js could already
+affect the execution of your Node.js applications in ways that
+are more severe than possible through these new attacks.
+
+This does not mean that you don't need to protect yourself from
+these new attacks when running Node.js applications. If an attacker
+manages to run malicious code on an upatched OS (whether using
+JavaScript or something else) they may be able to access memory and or
+data that they should not have access to.  In order to protect yourself
+from these cases, apply the security patches for your operating
+system. You do not need to update the Node.js runtime.
