+  <description>
+    <p>
+    Multiple integer overflows were reported, one of which Peter Valchev
+    (Google Security) found to be leading to a heap-based buffer overflow
+    in the cairo_image_surface_create_from_png() function that processes
+    PNG images.
+    </p>
+  </description>
+  <impact type="normal">
+    <p>
+    A remote attacker could entice a user to view or process a specially
+    crafted PNG image file in an application linked against Cairo, possibly
+    leading to 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 Cairo users should upgrade to the latest version:
+    </p>
+    <code>
+    # emerge --sync
+    # emerge --ask --oneshot --verbose &quot;&gt;=x11-libs/cairo-1.4.12&quot;</code>
