  <synopsis>
    Format string and Denial of Service vulnerabilities have been discovered in
    the monkeyd HTTP server, potentially resulting in the execution of
    arbitrary code.

    <p>
    monkeyd is a fast, efficient, small and easy to configure web server
    for Linux.

  <description>
    <p>
    Tavis Ormandy of the Gentoo Linux Security Audit Team discovered a
    double expansion error in monkeyd, resulting in a format string
    vulnerability. Ciaran McCreesh of Gentoo Linux discovered a Denial of
    Service vulnerability, a syntax error caused monkeyd to zero out
    unallocated memory should a zero byte file be requested.
    </p>
  </description>
  <impact type="high">
    <p>
    The format string vulnerability could allow an attacker to send a
    specially crafted request to the monkeyd server, resulting in the
    execution of arbitrary code with the permissions of the user running
    monkeyd. The DoS vulnerability could allow an attacker to disrupt the
    operation of the web server, should a zero byte file be accessible.
    </p>
  </impact>
  <workaround>
    <p>
    There is no known workaround at this time.
    </p>
  </workaround>
  <resolution>
    <p>
    All monkeyd users should upgrade to the latest version:
    </p>
    <code>
    # emerge --sync
    # emerge --ask --oneshot --verbose "&gt;=www-servers/monkeyd-0.9.1"</code>
  </resolution>
