+	<h1>Problem Description:</h1>
+	<p>The ggatec(8) daemon does not validate the size of a response before writing
+	it to a fixed-sized buffer.  This allows to overwrite the stack of ggatec(8).</p>
+	<h1>Impact:</h1>
+	<p>A malicious ggated(8) or an attacker in a priviledged network position can
+	overwrite the stack with crafted content and potentially execute arbitrary
+	code.</p>
