    gif2png is a command line program that converts image files from the
    Graphics Interchange Format (GIF) format to the Portable Network
    Graphics (PNG) format.

  <description>
    <p>
    gif2png contains a command line parsing vulnerability that may result
    in a stack overflow due to an unexpectedly long input filename.
    </p>
  </description>
  <impact type="normal">
    <p>
    A remote attacker could entice a user to open a specially crafted
    image, possibly resulting in the execution of arbitrary code with the
    privileges of the user running the application, or a Denial of Service.
    Note that applications relying on gif2png to process images can also
    trigger the vulnerability.
    </p>
  </impact>
  <workaround>
    <p>
    There is no known workaround at this time.
    </p>
  </workaround>
  <resolution>
    <p>
    All gif2png users should upgrade to the latest stable version:
    </p>
    <code>
    # emerge --sync
    # emerge --ask --oneshot --verbose &quot;&gt;=media-gfx/gif2png-2.5.1-r1&quot;</code>
  </resolution>
