  <background>
    <p>c-icap is an implementation of an ICAP server. It can be used with HTTP
      proxies that support the ICAP protocol to implement content adaptation
      and filtering services. 
    </p>
  </background>
  <description>
    <p>c-icap contains a flaw in the parse_request() function of request.c that
      may allow a remote denial of service. The issue is triggered when the
      buffer fails to contain a ‘ ‘ or ‘?’ symbol, which will cause the
      end pointer to increase and surpass allocated memory. With a specially
      crafted request (e.g. via the OPTIONS method), a remote attacker can
      cause a loss of availability for the program.
    </p>

  <impact type="normal">
    <p>A remote attacker may cause a Denial of Service condition.</p>
  </impact>
  <workaround>
    <p>There is no known workaround at this time.</p>
  </workaround>
  <resolution>
    <p>All c-icap users should upgrade to the latest version:</p>
    
    <code>
      # emerge --sync
      # emerge --ask --oneshot --verbose "&gt;=net-proxy/c-icap-0.2.6"
    </code>
