Description Arenas Belon, Carlo Marcelo 2000-09-05 07:45:59 UTC 
as explained on http://bugs.php.net/bugs.php?id=6496, a bug on the
generation of internal variables of PHP could be used to read any file on a
system (now on bugtraq)

php-4.0.2 is affected and previous versions should be also (tested on RC2
at least)

the attached patch fixes the problem.

upgrade to php-4.0.2 is a good idea too, spec on bug 17171 should be used
for this

An errata is being prepped.
Comment 3 Nalin Dahyabhai 2000-09-11 18:49:45 UTC 
Hang on -- the bug is only a problem on poorly-coded pages, and the fix in CVS
appears to actually break certain other things which it's not supposed to (which
looks like it might actually be a problem in the hash table implementation in
Zend).
Comment 4 Arenas Belon, Carlo Marcelo 2000-10-17 17:29:37 UTC 
obsoleted by 18965.
this patch is *somehow* included on 4.0.3pl1
