Because FreeRDP performs custom Common Name and DNS SAN string matching instead of using OpenSSL&#39;s length-aware identity validation APIs, it (1) truncates DNS SAN values at embedded NUL bytes (accepting e.g. &#39;victim.example\0.attacker.example&#39; as &#39;victim.example&#39;), (2) accepts a matching Common Name even when non-matching DNS SAN entries are present, and (3) accepts IP-literal targets via DNS/CN matching without comparing iPAddress SANs. Under a trusted or misissued certificate chain, an attacker positioned to present such a certificate can bypass server identity verification, weakening TLS server authentication.</p> <p><strong>Affected:</strong> FreeRDP</p> <p>FreeRDP before 3.29.0 (affected versions &lt;= 3.28.0) contains multiple TLS certificate identity validation weaknesses in tls_verify_certificate(), tls_match_hostname(), and x509_utils_get_dns_names().
