Descriptions

neon before 0.28.6, when OpenSSL or GnuTLS is used, does not properly handle a '\0' character in a domain name in the subject's Common Name (CN) field of an X.509 certificate, which allows 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.

neon, en versiones anteriores a la 0.28.6, cuando OpenSSL está habilitado, no maneja adecuadamente un caracter '\0' en un nombre de dominio, en el campo Common Name (CN) del asunto de un certificado X.509, lo cual permite a atacacantes 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 (CA) legítima, una cuestión relacionada con CVE-2009-2408.
