+  "details": "The ML-DSA verification algorithm as specified in [FIPS 204, subsection 6.3](https://nvlpubs.nist.gov/nistpubs/FIPS/NIST.FIPS.204.pdf#subsection.6.3) requires verifiers to check that the infinity norm of the deserialized signer response $z$ does not exceed $\\gamma_1 - \\beta$ (line 13 of Algorithm 8). The same check is required to be performed during signature generation.\n\nlibcrux-ml-dsa did not perform this check correctly during signature verification, accepting signatures with signer response norm above the allowed maximum value. The check is correctly performed during signing.\n\n## Impact\nApplications using libcrux-ml-dsa for signature verification would have accepted signatures that would be rejected by a conforming implementation.\n\n## Mitigation\nStarting from version `0.0.8`, signature verification uses the correct value for $\\gamma_1$ in the signer response norm check.",
