  <title>CUPS: Denial of Service</title>
  <synopsis>
    CUPS incorrectly handles partially-negotiated SSL connections allowing for
    a Denial of Service.

  <access>remote</access>
  <affected>
    <package name="net-print/cups" auto="yes" arch="*">
      <unaffected range="ge">1.2.9</unaffected>
      <vulnerable range="lt">1.2.9</vulnerable>
    </package>
  </affected>
  <background>
    <p>
    CUPS provides a portable printing layer for UNIX-based operating
    systems.
    </p>
  </background>
  <description>
    <p>
    CUPS does not properly handle partially-negotiated SSL connections.
    Upon receiving a partially-negotiated SSL connection, CUPS no longer
    accepts further incoming connections, as the initial connection never
    times out.
    </p>
  </description>
  <impact type="normal">
    <p>
    An attacker could partially negotiate an SSL connection with a CUPS
    server, and cause future connections to that server to fail, resulting
    in a Denial of Service.
    </p>
  </impact>
  <workaround>
    <p>
    There is no known workaround at this time.
    </p>
  </workaround>
  <resolution>
    <p>
    All CUPS users should upgrade to the latest version:
    </p>
    <code>
    # emerge --sync
    # emerge --ask --oneshot --verbose "&gt;=net-print/cups-1.2.9"</code>
  </resolution>
