    <p>
    Netpbm is a package of 220 graphics programs and a programming library,
    including pnmtopng, a tool to convert PNM image files to the PNG
    format.
    </p>
  </background>
  <description>
    <p>
    RedHat reported that pnmtopng is vulnerable to a buffer overflow.
    </p>
  </description>
  <impact type="normal">
    <p>
    An attacker could craft a malicious PNM file and entice a user to run
    pnmtopng on it, potentially resulting in the execution of arbitrary
    code with the permissions of the user running pnmtopng.
    </p>
  </impact>
  <workaround>
    <p>
    There is no known workaround at this time.
    </p>
  </workaround>
  <resolution>
    <p>
    All Netpbm users should upgrade to the latest version:
    </p>
    <code>
    # emerge --sync
    # emerge --ask --oneshot --verbose media-libs/netpbm</code>
  </resolution>
