Descripción
Se han descubierto múltiples vulnerabilidades en ProFTPD 1.3.0a y en versiones anteriores. Las vulnerabilidades son descritas a continuación:

- CVE-2006-6170: Se ha descubierto una vulnerabilidad de tipo desbordamiento de búfer. La vulnerabilidad reside en un error en la función "tls_x509_name_oneline()" en el módulo "mod_tls". Un atacante remoto podría ejecutar código arbitrario mediante un argumento de entrada con una extensión muy grande.

- CVE-2006-6171: Se ha descubierto un desbordamiento de búfer del tipo "off-by-two" en ProFTPD 1.3.0a y versiones anteriores. La vulnerabilidad reside en que PrfoFTPD establece incorrectamente el límite del búfer cuando CommandBufferSize está especificado en el archivo de configuración. Un atacante remoto podría causar una denegación de servicio y posiblemente ejecutar código arbitrario.
