Descriptions

Internet2 Shibboleth Service Provider software 1.3.x before 1.3.3 and 2.x before 2.2.1, when using PKIX trust validation, does not properly handle a '\0' character in the subject or subjectAltName fields of a certificate, which allows remote man-in-the-middle attackers to spoof arbitrary SSL servers via a crafted certificate issued by a legitimate Certification Authority, a related issue to CVE-2009-2408.

El software Internet2 Shibboleth Service Provider v1.3.x anterior a v1.3.3 y v2.x anterior a v2.2.1, cuando se utiliza la validación de confianza PKIX, no controla correctamente un caracter '\0' en los campos subject o subjectAltName de un certificado, lo cual permite a atacantes remotos hombre-en-el-medio (man-in-the-middle) suplantar servidores SSL a su elección a través de certificados manipulados expedidos por una Autoridad de Certificación, un tema relacionado con CVE-2009-2408.
