K46940010 : TMM vulnerability CVE-2018-5513

Security Advisory Description

A malformed Transport Layer Security (TLS) handshake causes the Traffic Management Microkernel (TMM) to stop responding, leading to a disruption of service. This issue is only exposed on the data plane when a Proxy SSL configuration is enabled. The control plane is not impacted by this issue. (CVE-2018-5513)

Impact

The BIG-IP system may temporarily fail to process traffic as it recovers from a TMM restart, and devices configured as a high availability (HA) pair may fail over.
