Descriptions

ProFTPD 1.3.0a and earlier does not properly set the buffer size limit when CommandBufferSize is specified in the configuration file, which leads to an off-by-two buffer underflow. NOTE: in November 2006, the role of CommandBufferSize was originally associated with CVE-2006-5815, but this was an error stemming from a vague initial disclosure. NOTE: ProFTPD developers dispute this issue, saying that the relevant memory location is overwritten by assignment before further use within the affected function, so this is not a vulnerability

** IMPUGNADO ** ProFTPD 1.3.0a y versiones anteriores no asigna apropiadamente el límite del búfer cuando se especifica CommandBufferSize en el fichero de configuración, lo que conduce a un desbordamiento inferior de búfer por superación de límite (off-by-twho).
NOTA: En Noviembre de 2006, el rol de CommandBufferSize fue originalmente asociado con CVE-2006-5815, lo cual fue erroneo debido a un vago descubrimiento inicial.
NOTA: Los desarrolladores de ProFTPD impugnaron esta vulnerabilidad, diciendo que la ubicación de memoria es sobre-escrita por asignación antes de ser usada con la función afectada, así que no es una vulnerabilidad.
