+    arbitrary code.

+    cstone and Richard Felker discovered a flaw in Screen's UTF-8 combining
+    character handling.
+    </p>
+  </description>
+  <impact type="high">
+    <p>
+    The vulnerability can be exploited by writing a special string of
+    characters to a Screen window. A remote attacker could cause a Denial
+    of Service or possibly execute arbitrary code with the privileges of
+    the user running Screen through a program being run inside a Screen
+    session, such as an IRC client or a mail client.
+    </p>
+  </impact>
+  <workaround>
+    <p>
+    There is no known workaround at this time.
+    </p>
+  </workaround>
+  <resolution>
+    <p>
+    All Screen users should upgrade to the latest version:
+    </p>
+    <code>
+    # emerge --sync
+    # emerge --ask --oneshot --verbose "&gt;=app-misc/screen-4.0.3"</code>
