Descriptions

sys/nfsclient/nfs_vfsops.c in the NFS client in the kernel in FreeBSD 7.2 through 8.1-PRERELEASE, when vfs.usermount is enabled, does not validate the length of a certain fhsize parameter, which allows local users to gain privileges via a crafted mount request.

sys/nfsclient/nfs_vfsops.c en el cliente NFS en el kernel en FreeBSD v7.2 hasta v8.1-PRERELEASE, cuando vfs.usermount está habilitado no valida la longitud de ciertos parámetros fhsize, lo que permite a usuarios locales obtener privilegios a través de una petición mount manipulada.
