CVE-2022-25638: Improper Certificate Validation

February 24, 2022 (updated March 4, 2022)

In wolfSSL before 5.2.0, certificate validation may be bypassed during attempted authentication by a TLS 1.3 client to a TLS 1.3 server. This occurs when the sig_algo field differs between the certificate_verify message and the certificate message.
