Problem Description:

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.

Impact:

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.
