[binary] A Ghostscript RCE and a Windows Registry Bug

Day[0]

This week's binary exploitation episode has some pretty solid bugs.A string escaping routine that goes out of bounds, a web-based information disclosure. And a couple kernel issues, one in the Windows registry, a logical bug leading to memory corruption, and an AppleSPU out of bounds access.
