CVE-2019-6594

On BIG-IP 11.5.1-11.6.3.2, 12.1.3.4-12.1.3.7, 13.0.0 HF1-13.1.1.1, and 14.0.0-14.0.0.2, Multi-Path TCP MPTCP does not protect against multiple zero length DATAFINs in the reassembly queue, which can lead to an infinite loop in some circumstances...

The vulnerability of the kernel of Linux and FreeBSD systems lies in errors in the algorithms used for reassembling packages in TCP stacks, which allows a hacker to cause a service failure.

The vulnerability of the kernel of Linux and FreeBSD systems is related to errors in the algorithms used for repackaging packages in TCP stacks. Exploiting this vulnerability allows a remote attacker to cause service interruptions through specially crafted traffic...
