I understand the concern about pov viruses, but perhaps this should be
discussed more privately with the POV-Team. With the recent similar
discussion in advanced.users, even the stupidest pov user (who, like me,
didn't have the slightest clue about potential pov viruses and didn't even
imagine why someone would want to create viruses with pov instead of making
pictures) has now received quite interesting instructions about how to make
one. And we don't want this, do we ?

I dunno. Does it? I've never tried and I don't plan to. However, I might
remove the ability to do Post_Scene_Command (and Pre_Scene_Command and any
other ini options that don't apply) from the ini_option keyword. Anyway,
someone could already put that in an INI file that comes with a POV file and
most people would never think to look in it.

No we certainly do not want anything like this to happen. If they do start
happening we will know who to blame... > Nieminen Juha wrote:

Can you please email me those files. I'll do my best to fix it. I have an
older version of stsky.pov but it doesn't have this problem.

This reminds me.... A while back somebody said they had changed the
radiosity code to do a better job of saving/loading the radiosity cache
file. Now, these changes never made it into POV 3.1g, so I don't have them.
If this bug is in UVPov, it is probably also in 3.1g. Does anybody have
that radiosity code? If not, I may be able to make those changes myself,
but for now I'm sure if you delete that cache file after canceling a trace,
the problem will go away.

Security through obscurity is usually not a good tactic to adopt.

OK, let's formulate it as follows : if you have a house and discover a special
fun way to go in without using the key, will you put a big sign on the door
saying "Hey, it's terrible, my door has to be fixed, everybody can go in, and I'm
going to tell you exactly how to do it because it's soooo cool !". If you really
think it 's OK to do so, you'd better discuss it with your insurance company...
You'll just tell your family and other people you trust and report the matter to
a locksmith. When a security flaw is discovered, the logical tactic is to keep
quiet and report them discreetly to the people who can fix it, and NOT to educate
potential intruders. The only time when it may be mandatory to go public in such
a detailed way is when the people in charge don't care about the problem or don't
want to know about it, and as far as I know this has not been the case here.

Please don't confuse viruses with trojans.
A virus is a code that tries to spread itself by attaching itself to other
files of the same kind. Usually this infection is intended to be as invisible
as possible. Sometimes the virus can do some harm (intentionally or not) but
most of the time it tries not to, so that it can spread itself as much as
possible. Currently I don't know of any reasonable way of making a povray
virus.
A trojan is just a program that seems to be ok, but when executed it makes
some harm. It doesn't spread itself, it just destroys everything it can.
As we have seen, trojans are quite easy to make with povray. And they can be
done in a way that they are _really_ hard to detect by examining the code
before rendering it.

Cover-up is not the answer.
Everyone with a minimal knowledge of C, delphi or visual basic can very
easyly make a trojan. We don't make any good by not telling anyone.
People should know what harm can be done so that they can be aware and
not execute/render everything they download. People can't be cautious of
something they don't know.
People should only execute or render things that come from trustworthy
persons, like me ;)

You can try it with a harmless command, like:
ini_option "Post_Scene_Command=echo hello > hello.txt"
If after rendering there is a file called "hello.txt" which contains the
word "hello", then it works.

I think it would be a good idea.

But at least we have one problem less. The smaller the amount of problems,
the better.
I never use a strange .ini file before looking at it. No-one should.
