(Ilia) > [/quote] > Taking into account that the vulnerability you describe is fixed in Hardened-PHP for years and that there is also a protection against this in the Suhosin Extension you can be sure that this NOT a new vulnerability (and that you are not the first one who found it...) For the record, the same vulnerability was reported by me on the 23.10.2004 at 22:05 in a mail to security@xxxxxxx (before I added the protection to Hardened-PHP) At that time the PHP developers considered it NOT A VULNERABILITY. Well now the PHP developers have commited a fix for this to the PHP CVS, crediting you instead of the original reporter (me) and as usual the fix is only fixing a part of the problem.
