Dear bipin gautam,

Of  cause, I experimented and found maximal value for IE 5 (2999999). In
my  tests  result was different from freezing PC (on S3 and VooDoo cards
under  NT  4.0) to only freezing IE itself (probably some Intel cards on
Windows  9x),  but  I did my tests for only Windows NT and 95/98 (it was
early  2000).  I  did not large research, because 4 years ago ability to
crash  host  remotely  via  client application was never considered as a
security  bug  (even  DoS  attacks  against server applications were not
treated  seriously  and  only  Gunninski care about things like crossite
scripting, this term became widely used later).

Sorry,  I  never  meant  to  blame  you  in stealing this information or
something. It was good catch and it's very common situation same problem
is  rediscovered  after  few  years  (I  was  in this situation for many
times). I'm just curious about same bug still unpatched for over 4 years
and  how  different  reaction  was  now  and 4 years ago. It's a kind of
nostalgie.  I  bet  with  this  tendencies in 2010 most bugs reported on
security  lists  are  something like interface spoofing, ineffective CPU
and  memory  usage,  etc.  World  is  changing :) It's time to release a
couple  of advisories for things never treated seriously before to check
reaction.
