Description
==========
- CVE-2015-8126:

Buffer overflow vulnerabilities in functions png_get_PLTE/png_set_PLTE,
allowing remote attackers to cause DoS to application or have
unspecified other impact. 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.
