Buffer overflow in HECI subsystem in Intel(R) CSME before versions 11.8.60, 11.11.60, 11.22.60 or 12.0.20 and Intel(R) TXE version before 3.1.60 or 4.0.10, or Intel(R) Server Platform Services before version 5.00.04.012 may allow an unauthenticated user to potentially execute arbitrary code via physical access.
The product performs operations on a memory buffer, but it reads from or writes to a memory location outside the buffer's intended boundary. This may result in read or write operations on unexpected memory locations that could be linked to other variables, data structures, or internal program data.
