SCA: security update for github.com/google/go-tpm (GHSA-5x29-3hr9-6wpw)

high Tenable Cloud Security Plugin ID 433601

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - An improperly initialized 'migrationAuth' value in Google's go-tpm TPM1.2 library versions prior to 0.3.0
 can lead an eavesdropping attacker to discover the auth value for a key created with CreateWrapKey. An
 attacker listening in on the channel can collect both 'encUsageAuth' and 'encMigrationAuth', and then can
 calculate 'usageAuth ^ encMigrationAuth' as the 'migrationAuth' can be guessed for all keys created with
 CreateWrapKey. TPM2.0 is not impacted by this. We recommend updating your library to 0.3.0 or later, or,
 if you cannot update, to call CreateWrapKey with a random 20-byte value for 'migrationAuth'.
 (CVE-2020-8918)
