  <title>ncpfs: Multiple vulnerabilities</title>
  <synopsis>
    The ncpfs utilities contain multiple flaws, potentially resulting in the
    remote execution of arbitrary code or local file access with elevated
    privileges.

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

  <description>
    <p>
    Erik Sjolund discovered two vulnerabilities in the programs
    bundled with ncpfs: there is a potentially exploitable buffer overflow
    in ncplogin (CAN-2005-0014), and due to a flaw in nwclient.c, utilities
    using the NetWare client functions insecurely access files with
    elevated privileges (CAN-2005-0013).
    </p>
  </description>
  <impact type="normal">
    <p>
    The buffer overflow might allow a malicious remote NetWare server
    to execute arbitrary code on the NetWare client. Furthermore, a local
    attacker may be able to create links and access files with elevated
    privileges using SUID ncpfs utilities.
    </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 "&gt;=net-fs/ncpfs-2.2.6"</code>
  </resolution>
