  <title>ncpfs: Buffer overflow in ncplogin and ncpmap</title>
  <synopsis>
    ncpfs is vulnerable to a buffer overflow that could lead to local execution
    of arbitrary code with elevated privileges.

    <p>
    ncpfs is a NCP protocol network filesystem that allows access to
    Netware services, for example to mount volumes of NetWare servers or
    print to NetWare print queues.

  <description>
    <p>
    Karol Wiesek discovered a buffer overflow in the handling of the
    '-T' option in the ncplogin and ncpmap utilities, which are both
    installed as SUID root by default.
    </p>
  </description>
  <impact type="high">
    <p>
    A local attacker could trigger the buffer overflow by calling one
    of these utilities with a carefully crafted command line, potentially
    resulting in execution of arbitrary code with root privileges.
    </p>
  </impact>
  <workaround>
    <p>
    There is no known workaround at this time.
    </p>
  </workaround>
  <resolution>
    <p>
    All ncpfs users should upgrade to the latest version:
    </p>
    <code>
    # emerge --sync
    # emerge --ask --oneshot --verbose &quot;&gt;=net-fs/ncpfs-2.2.5&quot;</code>
  </resolution>
