Descriptions

The cert_TestHostName function in lib/certdb/certdb.c in the certificate-checking implementation in Mozilla Network Security Services (NSS) before 3.16 accepts a wildcard character that is embedded in an internationalized domain name's U-label, which might allow man-in-the-middle attackers to spoof SSL servers via a crafted certificate.

La función cert_TestHostName en lib/certdb/certdb.c en la implementación de comprobación de certificado en Mozilla Network Security Services (NSS) anterior a 3.16 acepta un carácter comodín que está embebido en U-label de un nombre de dominio internacionalizado, lo que podría permitir a atacantes man-in-the-middle falsificar servidores SSL a través de un certificado manipulado.

It was found that the implementation of Internationalizing Domain Names in Applications (IDNA) hostname matching in NSS did not follow the RFC 6125 recommendations. This could lead to certain invalid certificates with international characters to be accepted as valid.
