Field upgrade is the TCG term for updating the TPM firmware. The update can be between TPM 1.2 and TPM 2.0, or between firmware versions. Some vendors limit the number of transitions between 1.2 and 2.0, and some restrict rollback to previous versions. [citation needed] Platform OEMs such as HP [85] supply an upgrade tool.
The vulnerability arises from an approach to RSA key generation used in vulnerable versions of the software library RSALib provided by Infineon Technologies and incorporated into many smart cards, Trusted Platform Modules (TPM), and Hardware Security Modules (HSM), including YubiKey 4 tokens when used to generate RSA keys on-chip for OpenPGP or ...
