Stefan Berger 9f740868fc swtpm: Check header size indicator against expected size (CID 375869) 
This fix addresses Coverity issue CID 375869.

Check the header size indicated in the header of the state against the
expected size and return an error code in case the header size indicator
is different. There was only one header size so far since blobheader was
introduced, so we don't need to deal with different sizes.

Without this fix a specially craft header could have cause out-of-bounds
accesses on the byte array containing the swtpm's state.

SWTPM - Software TPM Emulator
      David Safford safford@us.ibm.com
      Stefan Berger stefanb@us.ibm.com

The SWTPM package provides TPM emulators with different front-end interfaces
to libtpms. TPM emulators provide socket interfaces (TCP/IP and Unix) and
the Linux CUSE interface for the creation of multiple native /dev/vtpm* devices.

The SWTPM package also provides several tools for using the TPM emulator,
creating certificates for a TPM, and simulating the manufacturing of
a TPM by creating a TPM's EK and platform certificates etc. Please read 
the READMEs in the individual tool's directory under src/.

Please consult the Wiki for information about swtpm:
