    framebuffer console.

  <description>
    <p>
    Toth Andras has discovered a typographic mistake in the "fbgs" script,
    shipped with fbida if the "fbcon" and "pdf" USE flags are both enabled.
    This script runs "gs" without the -dSAFER option, thus allowing a
    PostScript file to execute, delete or create any kind of file on the
    system.
    </p>
  </description>
  <impact type="normal">
    <p>
    A remote attacker can entice a vulnerable user to view a malicious
    PostScript or PDF file with fbgs, which may result with the execution
    of arbitrary code.
    </p>
  </impact>
  <workaround>
    <p>
    There is no known workaround at this time.
    </p>
  </workaround>
  <resolution>
    <p>
    All fbida users with the "fbcon" and "pdf" USE flags both enabled
    should upgrade to the latest version:
    </p>
    <code>
    # emerge --sync
    # emerge --ask --oneshot --verbose "&gt;=media-gfx/fbida-2.03-r4"</code>
