Synopsis
========

Multiple vulnerabilities have been discovered in nfs-utils that could
lead to a Denial of Service, or the execution of arbitrary code.

Background
==========

nfs-utils is a package containing the client and daemon implementations
for the NFS protocol.

Affected packages
=================

    -------------------------------------------------------------------
     Package           /  Vulnerable  /                     Unaffected
    -------------------------------------------------------------------
  1  net-fs/nfs-utils     < 1.0.6-r6                       >= 1.0.6-r6

Description
===========

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.

Resolution
==========

All nfs-utils users should upgarde to the latest version:

    # emerge --sync
    # emerge --ask --oneshot --verbose ">=net-fs/nfs-utils-1.0.6-r6"
