Title
OOB Read in DoTls13CertificateVerify with WOLFSSL_DUAL_ALG_CERTS
Summary
Dual-Algorithm CertificateVerify out-of-bounds read. When processing a dual-algorithm CertificateVerify message, an out-of-bounds read can occur on crafted input. This can only occur when --enable-experimental and --enable-dual-alg-certs is used when building wolfSSL.
