F5 Networks BIG-IP : Excess resource consumption due to low MSS values vulnerability (K35421172)

Jonathan Looney discovered that the Linux kernel default MSS is hard-coded to 48 bytes. This allows a remote peer to fragment TCP resend queues significantly more than if a larger MSS were enforced. A remote attacker could use this to cause a denial of service. This has been fixed in stable kerne...

kernel: tcp: excessive resource consumption for TCP connections with low MSS allows remote denial of service

An excessive resource consumption flaw was found in the way the Linux kernel's networking subsystem processed TCP segments. If the Maximum Segment Size MSS of a TCP connection was set to low values, such as 48 bytes, it can leave as little as 8 bytes for the user data, which significantly increas...
