  <title>nfs-utils: Multiple remote vulnerabilities</title>
  <synopsis>
    Multiple vulnerabilities have been discovered in nfs-utils that could lead
    to a Denial of Service, or the execution of arbitrary code.

    <package name="net-fs/nfs-utils" auto="yes" arch="*">

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

  <description>
    <p>
    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.
    </p>
  </description>
  <impact type="high">
    <p>
    A remote attacker could potentially cause a Denial of Service, or
    even execute arbitrary code (64-bit architectures only) on a remote NFS
    server.
    </p>
  </impact>
  <workaround>
    <p>
    There is no known workaround at this time.
    </p>
  </workaround>
  <resolution>
    <p>
    All nfs-utils users should upgarde to the latest version:
    </p>
    <code>
    # emerge --sync
    # emerge --ask --oneshot --verbose &quot;&gt;=net-fs/nfs-utils-1.0.6-r6&quot;</code>
  </resolution>
