  <title>NX: User-assisted execution of arbitrary code</title>
  <synopsis>
    NX uses code from the X.org X11 server which is prone to multiple
    vulnerabilities.

    <p>
    NoMachine's NX establishes remote connections to X11 desktops over
    small bandwidth links. NX and NX Node are the compression core
    libraries, whereas NX is used by FreeNX and NX Node by the binary-only
    NX servers.
    </p>

  <description>
    <p>
    Multiple integer overflow and buffer overflow vulnerabilities have been
    discovered in the X.Org X server as shipped by NX and NX Node
    (vulnerabilities 1-4 in GLSA 200801-09).
    </p>
  </description>
  <impact type="normal">
    <p>
    A remote attacker could exploit these vulnerabilities via unspecified
    vectors, leading to the execution of arbitrary code with the privileges
    of the user on the machine running the NX server.
    </p>
  </impact>
  <workaround>
    <p>
    There is no known workaround at this time.
    </p>
  </workaround>
  <resolution>
    <p>
    All NX Node users should upgrade to the latest version:
    </p>
    <code>
    # emerge --sync
    # emerge --ask --oneshot --verbose "&gt;=net-misc/nxnode-3.1.0-r2"</code>
