Subject: [PATCH] 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.
|
||||
