+	<p>Daniel Knoppel reports:</p>
+	<blockquote cite="https://blog.phusion.nl/2015/12/07/cve-2015-7519/">
+	  <p>It was discovered by the SUSE security team that it was possible,
+	    in some cases, for clients to overwrite headers set by the server,
+	    resulting in a medium level security issue. CVE-2015-7519 has been
+	    assigned to this issue.</p>
+	  <p>Affected use-cases:</p>
+	  <p>Header overwriting may occur if all of the following conditions are met:</p>
+	  <ul>
+	    <li>Apache integration mode, or standalone+builtin engine without
+	      a filtering proxy</li>
+	    <li>Ruby or Python applications only (Passenger 5); or any
+	      application (Passenger 4)</li>
+	    <li>The app depends on a request header containing a dash (-)</li>
+	    <li>The header is supposed to be trusted (set by the server)</li>
+	    <li>The client correctly guesses the header name</li>
+	  </ul>
+	  <p>This vulnerability has been fixed by filtering out client headers
+	    that do not consist of alphanumeric/dash characters (Nginx already
+	    did this, so Passenger+Nginx was not affected). If your application
+	    depends on headers that don't conform to this, you can add a
+	    workaround in Apache specifically for those to convert them to a
+	    dash-based format.</p>
