In BIG-IP Versions 16.1.x before 16.1.3.1 and 15.1.x before 15.1.6.1, when an LTM Client or Server SSL profile with TLS 1.3 enabled is configured on a virtual server, along with an iRule that calls HTTP::respond, undisclosed requests can cause the Traffic Management Microkernel (TMM) to terminate. Note: Software versions which have reached End of Technical Support (EoTS) are not evaluated.
