  <description>
    <p>
    Diego E. Petteno` reported multiple integer overflows in glib/gbase64.c
    when converting a long string from or to a base64 representation.
    </p>
  </description>
  <impact type="normal">
    <p>
    A remote attacker could entice a user or automated system to perform a
    base64 conversion via an application using GLib, possibly resulting in
    the execution of arbitrary code.
    </p>
  </impact>
  <workaround>
    <p>
    There is no known workaround at this time.
    </p>
  </workaround>
  <resolution>
    <p>
    All GLib 2.18 users should upgrade to the latest version:
    </p>
    <code>
    # emerge --sync
    # emerge --ask --oneshot --verbose &quot;&gt;=dev-libs/glib-2.18.4-r1&quot;</code>
    <p>
    All GLib 2.16 users should upgrade to the latest version:
    </p>
    <code>
    # emerge --sync
    # emerge --ask --oneshot --verbose &quot;&gt;=dev-libs/glib-2.16.6-r1&quot;</code>
