I found a crash bug in pngcrush that is most likely exploitable and wanted to get a CVE assignment for it. I've already been in contact with the pngcrush author and this bug has been fixed in pngcrush v1.7.84 (which was released today, no mention of this in the changelog though: http://sourceforge.net/p/pmt/news/2015/02/pngcrush-1784-released/).
Access violation on destination operand
Exploitability Classification: EXPLOITABLE Explanation: The target crashed on an access violation at an address matching the destination operand of the instruction. This likely indicates a write access violation, which means the attacker may control the write address and/or value.
I've attached the test case but here is a hexdump: 0000000 4d8a 474e 0a0d 0a1a 0000 0000 3030 3030 0000010
