+  <description>
+    <p>
+    Reinhard Max discovered a boundary error in Tk when processing an
+    interlaced GIF with two frames where the second is smaller than the
+    first one.
+    </p>
+  </description>
+  <impact type="normal">
+    <p>
+    A remote attacker could entice a user to open a specially crafted GIF
+    image with a Tk-based software, possibly resulting in the execution of
+    arbitrary code with the privileges of the user running the application.
+    </p>
+  </impact>
+  <workaround>
+    <p>
+    There is no known workaround at this time.
+    </p>
+  </workaround>
+  <resolution>
+    <p>
+    All Tk users should upgrade to the latest version:
+    </p>
+    <code>
+    # emerge --sync
+    # emerge --ask --oneshot --verbose "&gt;=dev-lang/tk-8.4.15-r1"</code>
