CVE-2025-11934
Improper Validation of Signature Algorithm Used in TLS 1.3 CertificateVerify
Résumé
Improper Validation of Signature Algorithm Used in TLS 1.3 CertificateVerify
Description d'origine
La description telle que publiée par la source (souvent en anglais).
Improper input validation in the TLS 1.3 CertificateVerify signature algorithm negotiation in wolfSSL 5.8.2 and earlier on multiple platforms allows for downgrading the signature algorithm used. For example when a client sends ECDSA P521 as the supported signature algorithm the server previously could respond as ECDSA P256 being the accepted signature algorithm and the connection would continue with using ECDSA P256, if the client supports ECDSA P256.
