Undisclosed traffic patterns received may cause a disruption of service to the Traffic Management Microkernel (TMM). This vulnerability affects TMM through a virtual server configured with a FastL4 profile. Traffic processing is disrupted while TMM restarts. This issue only impacts specific engineering hotfixes. NOTE: This vulnerability does not affect any of the BIG-IP major, minor or maintenance releases you obtained from downloads.f5.com. The affected Engineering Hotfix builds are as follows: Hotfix-BIGIP-14.1.2.1.0.83.4-ENG Hotfix-BIGIP-12.1.4.1.0.97.6-ENG Hotfix-BIGIP-11.5.4.2.74.291-HF2
