+  <background>
+    <p>
+    The GStreamer FFmpeg plugin uses code from the FFmpeg library to
+    provide fast colorspace conversion and multimedia decoders to the
+    GStreamer open source media framework.

+  <description>
+    <p>
+    The GStreamer FFmpeg plugin contains derived code from the FFmpeg
+    library, which is vulnerable to a heap overflow in the
+    "avcodec_default_get_buffer()" function discovered by Simon Kilvington
+    (see GLSA 200601-06).

+  <impact type="normal">
+    <p>
+    A remote attacker could entice a user to run an application using
+    the GStreamer FFmpeg plugin on a maliciously crafted PIX_FMT_PAL8
+    format image file (like PNG images), possibly leading to the execution
+    of arbitrary code with the permissions of the user running the
+    application.
+    </p>
+  </impact>
+  <workaround>
+    <p>
+    There is no known workaround at this time.
+    </p>
+  </workaround>
+  <resolution>
+    <p>
+    All GStreamer FFmpeg plugin users should upgrade to the latest
+    version:
+    </p>
+    <code>
+    # emerge --sync
+    # emerge --ask --oneshot --verbose "&gt;=media-plugins/gst-plugins-ffmpeg-0.8.7-r1"</code>
