CVE-2017-6159
F5 BIG-IP LTM, AAM, AFM, Analytics, APM, ASM, DNS, GTM, Link Controller, PEM, Websafe software version 12.0.0 to 12.1.2, 11.6.0 to 11.6.1 are vulnerable to a denial of service attack when the MPTCP option is enabled on a virtual server.
Does this matter?
Lower severity and a low EPSS score (1.59%). Track it; it rarely justifies an emergency change on its own.
