+	  <p>A Heap-based buffer overflow was found in the way libjpeg-turbo
+	  decompressed certain corrupt JPEG images in which the component count
+	  was erroneously set to a large value. An attacker could create a
+	  specially-crafted JPEG image that, when opened, could cause an
+	  application using libpng to crash or, possibly, execute arbitrary code
+	  with the privileges of the user running the application.</p>
