Descriptions
The makemask function in mountd.c in mountd in FreeBSD 7.4 through 8.2 does not properly handle a -network field specifying a CIDR block with a prefix length that is not an integer multiple of 8, which allows remote attackers to bypass intended access restrictions in opportunistic circumstances via an NFS mount request.
La función makemask en mountd.c en mountd en FreeBSD v7.4 a v8.2 no controla correctamente el campo de una red, la especificación de un bloque CIDR con una longitud de prefijo que no es un múltiplo entero de 8, lo que permite a atacantes remotos evitar las restricciones de acceso previsto en oportunistas circunstancias a través de un montaje de petición NFS.
