  <background>
    <p>HAProxy is a TCP/HTTP reverse proxy for high availability environments.</p>
  </background>
  <description>
    <p>A boundary error in HAProxy could cause a buffer overflow when header
      rewriting is enabled and the configuration sets global.tune.bufsize to a
      value greater than the default (16384 bytes).
    </p>
  </description>
  <impact type="high">
    <p>A remote attacker could possibly execute arbitrary code with the
      privileges of the process or cause a Denial of Service condition.
    </p>
  </impact>
  <workaround>
    <p>There is no known workaround at this time.</p>
  </workaround>
  <resolution>
    <p>All HAProxy users should upgrade to the latest version:</p>
    
    <code>
      # emerge --sync
      # emerge --ask --oneshot --verbose "&gt;=net-proxy/haproxy-1.4.21"
    </code>
