Opened: Jan 23, 2015 Severity: 2-Critical
Certain F5 appliances and blades implement the Always On Management functionality via a LOP (Lights Out Processor) or LBH (Lights Out Processor/Backplane Microcontroller Hybrid) device. Under rare conditions, if a critical kernel event occurs while the LOP/LBH firmware is being updated to a newer version, the LOP/LBH firmware image may become corrupted on the LOP/LBH device.
If the LOP/LBH firmware becomes corrupted, the LOP/LBH device does not function properly, affecting critical chassis-management functionality such as identification of platform details including a blade's current slot in the chassis, obtaining current license state, and monitoring of chassis health information.
This issue may occur on the following F5 Network appliances and blades: -- BIG-IP 2000-/4000-series, 5000-/7000-series, 10000-/12000-series appliances. -- VIPRION B2100, B2150, B2250 blades.
None.
LOP/LBH firmware updates are protected against rare corruption by critical kernel events.
