Ibm: >> Power System S1022s (9105-22b) Firmware Security Vulnerabilities
IBM PowerVM Hypervisor Platform KeyStore (PKS) and virtual TPM FW1110.00 through FW1110.20, FW1060.00 through FW1060.71, and FW950.00 through FW950.H2 use persistent storage key seeds that result in an AES key with reduced strength. An attacker with access to the service processor or HMC could exploit this weakness to derive the encryption key and access the data.

IBM Power Systems Firmware FW1120.00, FW1110.00 through FW1110.30, and FW1060.00 through FW1060.80 is affected by a vulnerability in the interface between the BMC/FSP and the host system. An attacker with service account or root access to the BMC/FSP can execute arbitrary code on the host system, giving full control over the host system and all hosted partitions, resulting in a confidentiality, integrity, and availability impact.

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.
