    <p>OCaml is a high-level, strongly-typed, functional, and object-oriented
      programming language from the ML family of languages.
    </p>

  <description>
    <p>A bad sanitization of environment variables: CAML_CPLUGINS,
      CAML_NATIVE_CPLUGINS and CAML_BYTE_CPLUGINS in the OCaml compiler allows
      the execution of raised privileges via external code.
    </p>
  </description>
  <impact type="high">
    <p>A local attacker, by using specially crafted environment variables,
      could possibly escalate privileges to the root group.
    </p>
  </impact>
  <workaround>
    <p>There is no known workaround at this time.</p>
  </workaround>
  <resolution>
    <p>All OCaml users should upgrade to the latest version:</p>
    
    <code>
      # emerge --sync
      # emerge --ask --oneshot --verbose "&gt;=dev-lang/ocaml-4.04.2"
    </code>
