+       <p>CVE for a vulnerability in libpng, all versions, in the
+       png_set_PLTE/png_get_PLTE functions.  These functions failed to check for
+       an out-of-range palette when reading or writing PNG files with a bit_depth
+       less than 8.  Some applications might read the bit depth from the IHDR
+       chunk and allocate memory for a 2^N entry palette, while libpng can return
+       a palette with up to 256 entries even when the bit depth is less than 8.</p>
