Trying to typeset the default ConTeXt Live

\starttext
Hello world!
\stoptext

I get the following message:

TeXExec | processing document 'texweb.tex'
TeXExec | no ctx file found
TeXExec | tex processing method: context
TeXExec | TeX run 1
TeXExec | writing option file texweb.top
TeXExec | using randomseed 884
TeXExec | tex engine: pdftex
TeXExec | tex format: cont-en
This is pdfTeXk, Version 3.141592-1.40.3 (Web2C 7.5.6)
  %&-line parsing enabled.
  (/opt/context/current/texmf/web2c/natural.tcx)
I can't find the format file `cont-en.fmt'!
TeXExec | runtime: 0.776454

It seems that it doesn't work. It happens also with XeTeX and LuaTeX.

Are you sure that users can access to http://live.contextgarden.net/? I 
think this would be a big security hole.

Right. Neither pdftex nor xetex (log file below) seem to work at 
http://live.contextgarden.net. LuaTeX works fine.

sorry, I misunderstand:(
(I thought Live==TeXLive)

However, such hole could exsist:

\starttext
\directlua0{os.exec("uname -a")}
Hello world!
\stoptext

part of the log:

Here is the log, please pay attention to the Luatools scanning path lines:

I think that this is a serious security risk. Replacing luatools 
--generate with any unix command works. I can cat files in /etc directory, 
so os.exec effectively gives me read access to the entire server.

Is there a luatex flag which can limit what os.exec can do?

Without os.exec, it is not lua any more --- and moreover,  many
ConTeXt MKIV functions depend on that.

As to the live, I think a patched Lua file (loslib.c) can solve this problem:
remove the line
  {"execute",   os_execute},
in the static const luaL_Reg syslib[].

Running a TeX server had been a very dangerous service since long ago
(even before the appearance of luatex):
You know in pdftex and xetex, there is also a register defined by the
WEB2C (\write18) which enables the users to perform the similar
tricks. Webadmins should turn off that feature to ensure safety. The
libraries like XPDF which tex programs are linked to also have very
serious security bugs. So all the binaries send to Live should have
all these features turned off.

Moreover, if we do that, ConTeXt will not adapt to the "stripped down" LuaTeX.
For example, mtxrun.lua contains many functions which depend on
os.execute, and it even created some synonames as well:
   if not os.exec  then os.exec  = os.execute end
   if not os.spawn then os.spawn = os.execute end
So, a simple line removal is not sufficient.

LuaTeX (and TeX/ConTeXt in general) is not compatible with security. The
cache for example must be writable for everyone. In my opinion, the only
options for live.contextgarden.net are:
- just don't care, if there is a problem, restore from backup
- chroot jail
- virtual machine with virtual disk in non-persistent mode (at boot time
  the disk is always a fresh installation)
- perhaps some other ideas...

But adding security to LuaTeX seems to me too much work (a lot of
exceptions, heavy security audit, problems with cache, problems with
compatibility, and so on...).

Cheers, Peter

maybe a bsd-like jail(8).
http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/jails-intro.html

It is said that linux-vserver had the same feature. I hadn't tried that yet.

btw, there should be a way for users to upload their files (like
images used in the document).

there are provisions in mkiv to turn off os.execute etc in a tex run; 
since we have mplib embedded, there is not much reason for os.execute 
anyway so i can consider a --secure switch for mtx-context

Depends a bit on how you define security but it is true that context
does not 'do well' in restricted environments. The luatex executable
actually has a --safer switch (a la ghostscript) but if it would be
turned on, context mkiv wouldn't work.

possible new approach, but I suspect it won't be implemented until
after a).

A variation of c) may well be possible. Actually, if we can find funding
we could even move contextgarden.net + context/maps.aanhet.net to a
dedicated server. I could easily arrange hardware and a hosting spot
for that, but we would have to set up some kind of paypal construct
to get the finances sorted out. Patrick, Mojca, Hans, if there is
interest is such a solution, just let me know, and I will investigate
further.


Best wishes,
Taco

Hi, Hans:

not that helpful. users can still use io.open("/etc/xxx", "r")  to
read files they want.
even if io.open is removed (impossible), we can still use \input /etc/xxx.
so a bsd jail(8)-like solution is indispensable.

btw, virtual machine is also a nice solution. Since each time it down,
reinstall a minimal operating system (like bsd base system) plus a
full working ConTeXt minimals won't take more than 3 minutes (1.5
minute to reinstall the operating system, and 1.5 minute to rsync the
source).

that's the same for pdftex/xetex

Right.

Well, for the new server I will chroot TeX, I am playing with it. So
until then a) is the approach (keep fingers crossed).

That is true.

>> - perhaps some other ideas...

Maybe I will run live on another machine, but first I will move all the
stuff to the new server (time is so precious these days...).

Hi,

I doubt that it will run on the garden server (no kernel modules etc).
But true, it would be a nice solution!

I've done limited tests at home and it worked wery well.
Setup is not so hard, but requires some FreeBSD knowledge.
I think should be the right solution.
