Descriptions

The mod_tls module in ProFTPD before 1.3.2b, and 1.3.3 before 1.3.3rc2, when the dNSNameRequired TLS option is enabled, does not properly handle a '\0' character in a domain name in the Subject Alternative Name field of an X.509 client certificate, which allows remote attackers to bypass intended client-hostname restrictions via a crafted certificate issued by a legitimate Certification Authority, a related issue to CVE-2009-2408.

El módulo mod_tls en ProFTPD anterior v1.3.2b, y v1.3.3 anterior v1.3.3rc2, cuando la opción dNSNameRequired TLS es activada, no maneja adecuadamente el caracter '/0' en un nombre de dominio, dentro del campo Subject Alternative Name de un certificado cliente X.509, lo que permite a atacantes remotos eludir las restricciones cliente-hostname a través de un certificado manipulado concedido por una Autoridad Certificadora legítima, esta relacionado con CVE-2009-2408.
