Description
In BIP-IP versions 17.0.x before 17.0.0.2, 16.1.x before 16.1.3.3, 15.1.x before 15.1.8.1, 14.1.x before 14.1.5.3, and all versions of 13.1.x, when OCSP authentication profile is configured on a virtual server, undisclosed requests can cause an increase in CPU resource utilization. Note: Software versions which have reached End of Technical Support (EoTS) are not evaluated.
