    Arjan van de Ven has discovered a buffer overflow on 64-bit
    architectures in 'rquota_server.c' of nfs-utils (CAN-2004-0946). A
    remotely exploitable flaw on all architectures also exists in the
    'statd.c' file of nfs-utils (CAN-2004-1014), which can be triggered by
    a mishandled SIGPIPE.
  
Impact :

    A remote attacker could potentially cause a Denial of Service, or
    even execute arbitrary code (64-bit architectures only) on a remote NFS
    server.
  
Workaround :

    There is no known workaround at this time."

"An updated nfs-utils package that fixes various security issues is now
available.

The nfs-utils package provides a daemon for the kernel NFS server and
related tools, providing a much higher level of performance than the
traditional Linux NFS server used by most users.

This package also contains the showmount program. Showmount queries
the mount daemon on a remote host for information about the NFS
(Network File System) server on the remote host.

SGI reported that the statd daemon did not properly handle the SIGPIPE
signal. A misconfigured or malicious peer could cause statd to crash,
leading to a denial of service. The Common Vulnerabilities and
Exposures project (cve.mitre.org) has assigned the name CVE-2004-1014
to this issue.

Arjan van de Ven discovered a buffer overflow in rquotad. On 64-bit
architectures, an improper integer conversion can lead to a buffer
overflow. An attacker with access to an NFS share could send a
specially crafted request which could lead to the execution of
arbitrary code. The Common Vulnerabilities and Exposures project
(cve.mitre.org) has assigned the name CVE-2004-0946 to this issue.

Additionally, this updated package addresses the following issues :

  - The UID of the nfsnobody account has been fixed for
    32-bit and 64-bit machines. Because the st_uid field of
    the stat structure is an unsigned integer, an actual
    value of -2 cannot be used when creating the account, so
    the decimal value of -2 is used. On a 32-bit machine,
    the decimal value of -2 is 65534 but on a 64-bit machine
    it is 4294967294. This errata enables the nfs-utils
    post-install script to detect the target architecture,
    so an appropriate decimal value is used.

All users of nfs-utils should upgrade to this updated package, which
resolves these issues."
