module (HSM) functionality are exposed and impacted by this issue.
(CVE-2018-5524)
Impact
Malformed Transport Layer Security (TLS) requests sent to virtual
servers using network HSM functionality may cause a degradation of
service.
Note: If the BIG-IP system is configured with both virtual servers
using network HSM functionality and virtual servers that do
notusenetwork HSM functionality, only the virtual servers using
network HSM are exposed to this vulnerability."
