  <description>
    <p>Multiple vulnerabilities have been discovered in Mono and Mono debugger.
      Please review the CVE identifiers referenced below for details.
    </p>
  </description>
  <impact type="high">
    <p>A remote attacker could execute arbitrary code, bypass general
      constraints, obtain the source code for .aspx applications, obtain other
      sensitive information, cause a Denial of Service, modify internal data
      structures, or corrupt the internal state of the security manager.
    </p>
    
    <p>A local attacker could entice a user into running Mono debugger in a
      directory containing a specially crafted library file to execute
      arbitrary code with the privileges of the user running Mono debugger.
    </p>
    
    <p>A context-dependant attacker could bypass the authentication mechanism
      provided by the XML Signature specification.
    </p>
  </impact>
  <workaround>
    <p>There is no known workaround at this time.</p>
  </workaround>
  <resolution>
    <p>All Mono debugger users should upgrade to the latest version:</p>
    
    <code>
      # emerge --sync
      # emerge --ask --oneshot --verbose "&gt;=dev-util/mono-debugger-2.8.1-r1"
    </code>
    
    <p>All Mono users should upgrade to the latest version:</p>
