libpng reports :
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.
