+    <p>A vulnerability has been reported in Tk, which can potentially be 
+      exploited by malicious people to compromise an application using the 
+      library.</p>
+    <p>The vulnerability is caused due to a boundary error within the 
+      "ReadImage()" function in generic/tkImgGIF.c. This can be exploited to 
+      cause a buffer overflow via interlaced GIF files containing multiple 
+      smaller frames following the first frame.</p>
+    <p>Successful exploitation may allow execution of arbitrary code.</p>
+    <p>The vulnerability is reported in versions prior to 8.4.16.</p>
