Descriptions

mod_nss 1.0.8 and earlier, when NSSVerifyClient is set to none for the server/vhost context, does not enforce the NSSVerifyClient setting in the directory context, which allows remote attackers to bypass intended access restrictions.

mod_nss 1.0.8 y anteriores versiones, cuando se establece NSSVerifyClient en none para el contexto del server/vhost, no aplica la opción de NSSVerifyClient en el contexto de directorio, lo que permite a atacantes remotos evadir restricciones de acceso intencionadas.
