Infineon TPM Vulnerability

The information below includes a description of the vulnerability and details the steps recommended by Infineon and Fujitsu that users should take to secure affected product lines.

Infineon TPM chipsets that come with many modern-day motherboards generate insecure RSA encryption keys that put devices at risk of attack. TPM stands for Trusted Platform Module (TPM), which is. Upgrading the Firmware on Infineon TPM's. In early October of 2017, researchers announced, publicly, a cryptographic vulnerability in the RSA generation algorithms found within practically every TPM, using Infineon's RSA library. This vulnerability would effectively allow an attacker to easily guess the private key component of the RSA key.

Summary:
A vulnerability in Infineon TPM hardware has been discovered recently with outdated TPM firmware using an algorithm that generates weaker RSA keys. This page provides information on how to update outdated TPM firmware.

A vulnerability was identified in the RSA key generation method used by Trusted Platform Modules (TPMs) manufactured by Infineon and contained in some Lenovo products. RSA public keys generated by the Infineon TPM for use by certain software programs should be considered insecure. No TPMs from other manufacturers are affected.

For more detailed information please refer to the Infineon web site.

Affected Products:
A number of Fujitsu products are affected by these vulnerabilities. Fujitsu is working to distribute patches for all affected products that are currently supported. Older systems that are no longer supported will not be patched.

Fujitsu is providing an easy to use Windows-based tool for end customers to identify whether a TPM is installed in their system. If the tool finds a TPM in the system, then it will show the relevant TPM and firmware version. This tool can be found here: TPM Information Tool
Please note: for some affected products, TPM was sold as an optional component. This means that not all systems are affected by this issue.

1. Please see FAI Mobile Downloads site for postings.
2. The FW Tool must be used with BIOS update, although the BIOS update can be applied separately.

WARNING:
Clearing the TPM resets it to factory defaults. All created keys will be deleted and you will therefore lose access to any data encrypted by those keys. For more detailed information regarding TPM Clear please refer also to the following Microsoft site.
