Summary

tpm2-tss security update

Details

tpm2-tss is a software stack supporting Trusted Platform Module(TPM) 2.0 system APIs which provides TPM2.0 specified APIs for applications to access TPM module through kernel TPM drivers.

Security Fix(es):

A flaw was found in the tpm2-tss package, where it was not checked to see if the magic number in the attest is equal to the TPM2_GENERATED_VALUE. This flaw allows an attacker to generate arbitrary quote data, which may not be detected by Fapi_VerifyQuote.(CVE-2024-29040)

Severity

5.5 (Medium)

CVE-2024-29040 (GCVE-0-2024-29040)

Vulnerability from cvelistv5 – Published: 2024-06-28 21:02 – Updated: 2025-11-04 17:19

Title

Fapi Verify Quote: Does not detect if quote was not generated by TPM

Summary

This repository hosts source code implementing the Trusted Computing Group's (TCG) TPM2 Software Stack (TSS). The JSON Quote Info returned by Fapi_Quote has to be deserialized by Fapi_VerifyQuote to the TPM Structure `TPMS_ATTEST`. For the field `TPM2_GENERATED magic` of this structure any number can be used in the JSON structure. The verifier can receive a state which does not represent the actual, possibly malicious state of the device under test. The malicious device might get access to data it shouldn't, or can use services it shouldn't be able to. This issue has been patched in version 4.1.0.

Severity

4.3 (Medium)
