This bug has been fixed in CVS.

In case this was a PHP problem, snapshots of the sources are packaged
every three hours; this change will be in the next snapshot. You can

With:

safe_mode = On
safe_mode_gid = On

The code below can browse any directory/file on the system.  This
mentions openbase_dir but one (at least I) would think Safe Mode would
have more power.  Safe mode is strict in some regards but super loose
in others it seems.

In the very least please explain this a bit so it can be documented. 
And btw, the following is in the _php_do_opendir code but what does it
do?

dirp = php_stream_opendir(Z_STRVAL_PP(arg),
ENFORCE_SAFE_MODE|REPORT_ERRORS, NULL);

Also AFICT this was suppose to be fixed:

Danielsan is right... i have had a short look into the sourcecode
(ext/standard/dir.c) and compared chdir-function with
opendir-function.

In PHP_FUNCTION(chdir) i found this three-liner which seems to be a
safe_mode-Check:
-------------------------
if (PG(safe_mode) && !php_checkuid((*arg)->value.str.val, NULL,
CHECKUI$
        RETURN_FALSE;
}
-------------------------

PHP_FUNCTION(opendir) (or _php_do_opendir() to which this function
refers) does not have such a check, just a short open_basedir-Check.
Oh, btw, it seems for me that chdir doesn't do a open_basedir-Check but
i may be wrong.

cu, Roland

PS: All what i said is just 'imho' and 'afaik' because i do not have
many expiences with C!

i did not test it, but 'looking at the source code' (TM)
seems you need to use open_basedir to limit opendir()
directory range.

On the same system (=same configuration) chdir() IS limited by
safe_mode, opendir() are readdir() are NOT. 

This is either a bug, or if it isn't, I'll make it a feature request.
Either way, it should be fixed, I think.

Kind Regards,

Sorry for the bogus.

Would you care to elaborate? I seem to be misunderstanding something. I
just don't understand why - with the same configuration - chdir() cares
about the UID, and opendir/readdir don't. chdir raises a "SAFE MODE
Restriction in effect" whereas readdir() and opendir() let me browse
through all directories where I have apache allowed to.

Thanks for your help.

Kind Regards,
  Daniel Lorch
