IBM PowerVM Hypervisor FW950.00 through FW950.E0, FW1050.00 through FW1050.50, and FW1060.00 through FW1060.40 could allow a local privileged user to cause a denial of service by issuing a specially crafted IBM i hypervisor call that would disclose memory contents or consume excessive memory resources.
IBM PowerVM Hypervisor FW1050.00 through FW1050.30 and FW1060.00 through FW1060.20 could allow a local user, under certain Linux processor combability mode configurations, to cause undetected data loss or errors when performing gzip compression using HW acceleration.
IBM PowerVM Platform KeyStore (IBM PowerVM Hypervisor FW950.00 through FW950.90, FW1030.00 through FW1030.60, FW1050.00 through FW1050.20, and FW1060.00 through FW1060.10 functionality can be compromised if an attacker gains service access to the HMC. An attacker that gains service access to the HMC can locate and through a series of service procedures decrypt data contained in the Platform KeyStore.
