Upgrade dcap-qvl to version 0.3.9 or higher.
Overview
dcap-qvl is a This crate implements the quote verification logic for DCAP (Data Center Attestation Primitives) in pure Rust. It supports both SGX (Software Guard Extensions) and TDX (Trust Domain Extensions) quotes.
Affected versions of this package are vulnerable to Improper Verification of Cryptographic Signature via the cryptographic verification process. An attacker can bypass remote attestation security by forging QE Identity data and whitelisting a malicious or unauthorized Quoting Enclave, allowing untrusted quotes to be accepted as valid by the verifier.
