The "exception analysis" is output from the WinDbg !analyze command run on a crash where access to the uninitialized memory ultimately corrupted the instruction pointer, leading to a data execution prevention crash. That's why the disassembly is junk--the IP is not pointing to valid instructions. This crash was provided as an example because it demonstrates that the issue is likely exploitable, and can probably be used to achieve code execution.

Here is an example of a crash where execution halts immediately upon attempted to dereference a corrupted pointer. Note that the pointer is 0xC0C0C0C0--a fill pattern indicative of uninitialized memory.
