Improper Validation of Signature Algorithm Used in TLS 1.3 CertificateVerify
概要
Improper Validation of Signature Algorithm Used in TLS 1.3 CertificateVerify
原文の説明
取得元が公開している説明をそのまま載せています (多くは英語)。
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.
