+ <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>
