Descriptions

The ExpandCert function in Apache-SSL before apache_1.3.41+ssl_1.59 does not properly handle (1) '/' and (2) '=' characters in a Distinguished Name (DN) in a client certificate, which might allow remote attackers to bypass authentication via a crafted DN that triggers overwriting of environment variables.

La función ExpandCert en Apache-SSL versiones anteriores apache_1.3.41+ssl_1.59 no gestiona correctamente los caracteres (1) '/' y (2) '=' en un Distinguished Name (DN) de un certificado de cliente, lo cual puede permitir a atacantes remotos evitar autenticarse a través de un DN manipulado que dispara la sobreescritura de variables de entorno.
