Description

In F5 BIG-IP LTM, AAM, AFM, Analytics, APM, ASM, DNS, Edge Gateway, GTM, Link Controller, PEM, Websafe software version 12.0.0 to 12.1.2, 11.6.0 to 11.6.1, 11.4.0 to 11.5.4, 11.2.1, in some cases TMM may crash when processing TCP traffic. This vulnerability affects TMM via a virtual server configured with TCP profile. Traffic processing is disrupted while Traffic Management Microkernel (TMM) restarts. If the affected BIG-IP system is configured to be part of a device group, it will trigger a failover to the peer device. (CVE-2017-6162)

Impact

This vulnerability affects the Traffic Management Microkernel (TMM) througha virtual server configured with a TCP profile. Traffic processing is disrupted while TMMrestarts. If the affected BIG-IP system is configured as part of a device group, the systemwill trigger a failover to the peer device.
