  <background>
    <p>nginx is a robust, small, and high performance HTTP and reverse proxy
      server.
    </p>

  <description>
    <p>Multiple vulnerabilities have been found in nginx:</p>
    
    <ul>
      <li>The TLS protocol does not properly handle session renegotiation
        requests (CVE-2009-3555).
      </li>
      <li>The "ngx_http_process_request_headers()" function in ngx_http_parse.c
        could cause a NULL pointer dereference (CVE-2009-3896).
      </li>
      <li>nginx does not properly sanitize user input for the the WebDAV COPY
        or MOVE methods (CVE-2009-3898).
      </li>
      <li>The "ngx_resolver_copy()" function in ngx_resolver.c contains a
        boundary error which could cause a heap-based buffer overflow
        (CVE-2011-4315).
      </li>
      <li>nginx does not properly parse HTTP header responses which could
        expose sensitive information (CVE-2012-1180).
      </li>
    </ul>
  </description>
  <impact type="high">
    <p>A remote attacker could possibly execute arbitrary code with the
      privileges of the nginx process, cause a Denial of Service condition,
      create or overwrite arbitrary files, or obtain sensitive information. 
    </p>
  </impact>
  <workaround>
    <p>There is no known workaround at this time.</p>
  </workaround>
  <resolution>
    <p>All nginx users should upgrade to the latest version:</p>
    
    <code>
      # emerge --sync
      # emerge --ask --oneshot --verbose "&gt;=www-servers/nginx-1.0.14"
    </code>
    
  </resolution>
