Descriptions

The C client and C-based client bindings in the Apache Qpid Proton library before 0.13.1 on Windows do not properly verify that the server hostname matches a domain name in the subject's Common Name (CN) or subjectAltName field of the X.509 certificate when using the SChannel-based security layer, which allows man-in-the-middle attackers to spoof servers via an arbitrary valid certificate.

El cliente en C y basado en C, en la librería Apache Qpid Proton anterior a la versión 0.13.1 en Windows no verifica correctamente que el nombre de host del servidor coincide con un nombre de dominio en el Common Name (CN) del asunto o en el campo subjectAltName del certificado X.509 cuando se utiliza una capa de seguridad basada en SChannel, lo que permite a atacantes miTm suplantar servidores a través de un certificado válido.
