File 0003-tpm2-Restore-original-value-if-unmarsalled-value-was.patch of Package libtpms
From 2e6173c273ca14adb11386db4e47622552b1c00e Mon Sep 17 00:00:00 2001 From: Stefan Berger <stefanb@linux.vnet.ibm.com> Date: Wed, 23 Jun 2021 20:54:44 -0400 Subject: [PATCH 3/3] tpm2: Restore original value if unmarsalled value was illegal Restore the original value of the memory location where data from a stream was unmarshalled and the unmarshalled value was found to be illegal. The goal is to not keep illegal values in memory.
