  <background>
    <p>LZO is an extremely fast compression and decompression library</p>
  </background>
  <description>
    <p>LZO is vulnerable to an integer overflow condition in the
      “lzo1x_decompress_safe” function which could result in a possible
      buffer overrun when processing maliciously crafted compressed input data.
    </p>
  </description>
  <impact type="normal">
    <p>A remote attacker could send specially crafted compressed input data
      possibly resulting in a Denial of Service condition or arbitrary code
      execution.
    </p>
    
  </impact>
  <workaround>
    <p>There is no known workaround at this time.</p>
  </workaround>
  <resolution>
    <p>All LZO users should upgrade to the latest version:</p>
    
    <code>
      # emerge --sync
      # emerge --ask --oneshot --verbose "&gt;=dev-libs/lzo-2.08"
    </code>
