"In BIG-IP LTM, AAM, AFM, Analytics, APM, ASM, DNS, Link Controller,
PEM, and WebSafe software 12.0.0 to 12.1.1, in some cases the Traffic
Management Microkernel (TMM) may crash when processing fragmented
packets. This vulnerability affects TMM through a virtual server
configured with a FastL4 profile. Traffic processing is disrupted
while TMM restarts. If the affected BIG-IP system is configured as
part of a device group, it will trigger a failover to the peer device.
(CVE-2017-6166)
Impact
A remote attacker may be able to cause a BIG-IP system to produce a
core file, disrupting the flow of traffic and causing a failover to a
standby system, if configured. BIG-IP logs will show the notice panic:
packet_free: double free! error when TMM crashes."
