+	<h1>Problem Description:</h1>
+	<p>One of the data structures that holds TCP segments uses
+	an inefficient algorithm to reassemble the data. This causes
+	the CPU time spent on segment processing to grow linearly
+	with the number of segments in the reassembly queue.</p>
+	<h1>Impact:</h1>
+	<p>An attacker who has the ability to send TCP traffic to
+	a victim system can degrade the victim system's network
+	performance and/or consume excessive CPU by exploiting the
+	inefficiency of TCP reassembly handling, with relatively
+	small bandwidth cost.</p>
