[Full-disclosure] LSADump2 Crashing Windows

From: oh face (0h.fac3gmail.com)

In my recent experience, LSADump2 has been crashing Windows boxes. I was
able to verify this on fully patched Windows XP and 2003. In further
examination, LSADump2, when executed, killed the "lsass" process, and with
the "winlogon" process still running, the system was forced to reboot. As
far as I know, LSADump2 is utilizing a DLL injection technique to dump the
contents of LSA secrets.

Question:
1. Has anyone had this experience? If so, is there a safe method to execute
this tool?
2. When I tested LSADump2 on various Windows boxes, not all fully patched
boxes were affected by this issue. What configuration of Windows is exactly
causing "lsass" to fail?
