Descriptions

The nfsrvd_readdir function in sys/fs/nfsserver/nfs_nfsdport.c in the new NFS server in FreeBSD 8.0 through 9.1-RELEASE-p3 does not verify that a READDIR request is for a directory node, which allows remote attackers to cause a denial of service (memory corruption) or possibly execute arbitrary code by specifying a plain file instead of a directory.

La función nfsrvd_readdir en sys/fs/nfsserver/nfs_nfsdport.c en el nuevo servidor NFS en FreeBSD v8.0 a través de v9.1-RELEASE-p3 no verifica que la solicitud READDIR para un nodo de directorio, lo que permite a atacantes remotos provocar una denegación de servicio (corrupción de memoria) o posiblemente ejecutar código arbitrario mediante la especificación de un archivo sin formato en lugar de un directorio.
