+    gif2png contains a command line parsing vulnerability that may result
+    in a stack overflow due to an unexpectedly long input filename.
+    </p>
+  </description>
+  <impact type="normal">
+    <p>
+    A remote attacker could entice a user to open a specially crafted
+    image, possibly resulting in the execution of arbitrary code with the
+    privileges of the user running the application, or a Denial of Service.
+    Note that applications relying on gif2png to process images can also
+    trigger the vulnerability.
+    </p>
+  </impact>
+  <workaround>
+    <p>
+    There is no known workaround at this time.
+    </p>
+  </workaround>
+  <resolution>
+    <p>
+    All gif2png users should upgrade to the latest stable version:
+    </p>
+    <code>
+    # emerge --sync
+    # emerge --ask --oneshot --verbose &quot;&gt;=media-gfx/gif2png-2.5.1-r1&quot;</code>
