    <p>
    cmd5checkpw is a checkpassword compatible authentication program that
    uses CRAM-MD5 authentication mode.
    </p>
  </background>
  <description>
    <p>
    Florian Westphal discovered that cmd5checkpw is installed setuid
    cmd5checkpw but does not drop privileges before calling execvp(), so
    the invoked program retains the cmd5checkpw euid.
    </p>
  </description>
  <impact type="low">
    <p>
    Local users that know at least one valid /etc/poppasswd user/password
    combination can read the /etc/poppasswd file.
    </p>
  </impact>
  <workaround>
    <p>
    There is no known workaround at this time.
    </p>
  </workaround>
  <resolution>
    <p>
    All cmd5checkpw users should upgrade to the latest available version:
    </p>
    <code>
    # emerge --sync 
    # emerge --ask --oneshot --verbose "&gt;=net-mail/cmd5checkpw-0.22-r2"</code>
