Descriptions
The vfs_hang_addrlist function in sys/kern/vfs_export.c in the NFS server implementation in the kernel in FreeBSD 8.3 and 9.x through 9.1-RELEASE-p5 controls authorization for host/subnet export entries on the basis of group information sent by the client, which allows remote attackers to bypass file permissions on NFS filesystems via crafted requests.
La función vfs_hang_addrlist en sys/kern/vfs_export.c en la implementación del servidor NFS en el kernel de FreeBSD 8.3 y 9.x a la 9.1-RELEASE-p5 controla la autorización para exportar las entradas host/subnet en las bases del grupo de información enviado por el cliente, lo que permite a atacantes remotos evitar los permisos de ficheros en los sistemas NFS a través de peticiones manipuladas.
