Name of the Vulnerable Software and Affected Versions
versions prior to 0.9.0
Description
The intra-handshake attested TLS (aTLS) Intel TDX verification path fails to copy the expected current-session freshness value into the TDX quote-body policy before quote validation. Consequently, structurally valid TDX QuoteV4 Evidence is accepted without verifying that its
REPORT DATA field matches the reportData expected for the current session. This allows a relying party to accept Evidence with mismatched or reused reportData and release application data after the handshake, leading to session-misbinding to an unintended attestation context.Recommendations
Update to version 0.9.0.
