  <title>NX 2.1: User-assisted execution of arbitrary code</title>
  <synopsis>
    NX in the 2.1 series uses XFree86 4.3 code which is prone to an integer
    overflow vulnerability.

    <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.

  <description>
    <p>
    Chris Evans reported an integer overflow within the FreeType PCF font
    file parser (CVE-2006-1861). NX and NX Node are vulnerable to this due
    to shipping XFree86 4.3.0, which includes the vulnerable FreeType code.
    </p>
  </description>
  <impact type="normal">
    <p>
    A remote attacker could exploit these integer overflows by enticing a
    user to load a specially crafted PCF font file which might lead 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 users should upgrade to the latest version:
    </p>
    <code>
    # emerge --sync
    # emerge --ask --oneshot --verbose &quot;&gt;=net-misc/nx-3.0.0&quot;</code>
    <p>
    All NX Node users should upgrade to the latest version:
    </p>
    <code>
    # emerge --sync
    # emerge --ask --oneshot --verbose &quot;&gt;=net-misc/nxnode-3.0.0-r3&quot;</code>
