[comp.os.vms] SYS.EXE part of DEC security patch -- what is it?

SEYMOUR@phast.phys.washington.EDU (04/19/88)

tucked into the dec security patch is a replacement of a single
INSV instruction in the pagefault code with a two-instruction
"equivalent".  why?  is this part of the security, or is it a correction
of a bug in sys.exe?
