Power Systems Firmware FW1120.00, FW1110.00 through FW1110.30, and FW1060.00 through FW1060.80 is affected by a vulnerability in the host firmware boot process image validation path. An attacker with service access to the service processor can supply a maliciously crafted code update image, allowing arbitrary code to be executed on the host system. Successful exploitation could result in a confidentiality, integrity, and availability impact to the affected host system.
