Descriptions
sendmail before 8.14.4 does not properly handle a '\0' character in a Common Name (CN) field of an X.509 certificate, which (1) allows man-in-the-middle attackers to spoof arbitrary SSL-based SMTP servers via a crafted server certificate issued by a legitimate Certification Authority, and (2) allows remote attackers to bypass intended access restrictions via a crafted client certificate issued by a legitimate Certification Authority, a related issue to CVE-2009-2408.
sendmail anterior a v8.14.4 no maneja adecuadamente un carácter '\0' en un fichero Common Name (CN) de un certificado X.509; esto permite (1) a atacantes del tipo hombre-en-el-medio suplantar a su elección servidores SMTP basados en SSL utilizando un certificado de servidor manipulado expedido por una Autoridad Certificadora legítima y (2) a atacantes remotos evitar las restricciones de acceso pretendidas a través de un certificado cliente expedido por una Autoridad Certificadora legítima. Vulnerabilidad relacionada con CVE-2009-2408.
