Symptoms

TMM cores.

Impact

Processing of invalid length can cause memory corruption. The tmm process generates a core. Traffic disrupted while tmm restarts.

Conditions

-- Platform: B4400 Blade (BIG-IP VPR-B4450N). -- High availability (HA) mirroring is set up. -- Provisioned modules: LTM, AFM. -- HA mirroring messages are received with unexpected interface name length.

The system now validates the length of the interface name before processing the HA message at the receiver side and ignores the HA message if the interface name length is wrong.
