"Under limited conditions, an invalid TCP segment can lead to a Denial
of Service for the High-Speed Bridge (HSB) on the following platforms:
3900, 6900, 8900, 8950, 11000, 11050, PB100 or PB200. This issue is
only exposed on virtual servers while Software SYN cookies are
configured for use and currently engaged. The scope of the exposure is
limited to the BIG-IP data plane. The access vector is network based
and authentication is not a requirement for attack. There is no
control plane exposure to this issue. (CVE-2015-8099) Note : The
affected platforms do not support the Hardware SYN cookie protection
feature. This feature appears in the profile configuration; however,
it is not configurable for the noted platforms. For more information
about SYN cookie protection, refer to K14779: Overview of BIG-IP SYN
cookie protection (11.3.x - 12.x)."
