FreeBSD Security Advisory - FreeBSD-SA-18:08.tcp

Posted Aug 7, 2018

Authored by Juha-Matti Tilli | Site security.freebsd.org

FreeBSD Security Advisory - 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. 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.
