2013-05-071. Fix TOCTOU issue in VariableSmm, FtwSmm, FpdtSmm, SmmCorePerformance SMM ↵lzeng14
handler. For VariableSmm, pre-allocate a mVariableBufferPayload buffer with mVariableBufferPayloadSize(match with mVariableBufferPayloadSize in VariableSmmRuntimeDxe) to hold communicate buffer payload to avoid TOCTOU issue. 2. Add check to ensure CommBufferPayloadSize not exceed mVariableBufferPayloadSize or is enough to hold function structure in VariableSmm and FtwSmm. 3. Align FtwGetLastWrite() in FaultTolerantWriteSmmDxe.c to FtwGetLastWrite() in FaultTolerantWrite.c.

2013-04-251. Use the check IsAddressValid() to prevent SMM communication buffer ↵lzeng14
overflow in SmmVariable, FtwSmm, FpdtSmm, SmmCorePerformance and SmmBaseHelper, and add check to prevent InfoSize overflows in SmmVariableHandler. 2. Refine the debug message. 3. Add check to make sure the input VariableName is A Null-terminated string. 4. Use local variable to hold StrSize (VariableName) to avoid duplicated StrSize calculation.
