CVE Request: libpng 1.6.15 Heap Overflow

[endeavor <endeavor () rainbowsandpwnies com>]

I am requesting a CVE for a heap-overflow in libpng 1.6.15. It's my
understanding that versions 1.6.9-1.6.15 are vulnerable, and according to
patch notes it looks like some revisions in the 1.5 branch may have been
affected as well. However, I've only tested 1.6.15 and can only speak for
it.

Please let me know!
