FreeBSD : FreeBSD -- Resource exhaustion in TCP reassembly (3c2eea8c-99bf-11e8-8bee-a4badb2f4699)
Medium Nessus Plugin ID 111561
SynopsisThe remote FreeBSD host is missing one or more security-related updates.
DescriptionOne 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.
