Subject: [PATCH RESEND 0/2] Avoid sending invalid data to the TPM
Date: Thu, 24 Aug 2017 10:35:43 +0200	[thread overview]
Message-ID: <20170824083545.13280-1-Alexander.Steffen@infineon.com> (raw)

When trying to send invalid commands (with mismatching commandSize values)
to the TPM we discovered some cases in which data is sent to the TPM that
should not be sent there. Similar problems were fixed years ago, but this
one slipped through it seems.

  tpm-dev-common: Reject too short writes
