Signature Image System

Signature Image Management System (file based)

Updated: 27 June 2002, 12:22 AM BST

This hack allows users to upload a image or images that they can then use as part of the thier signature. All uploaded images are private to the user that uploaded them.

The hack requires that you have PHP 4.1.0 or newer for the upload functions to work correctly. PHP 4.0.6 can be used with modifications (not recommended).

The scripts can if enabled also prevent users from externally linking to the images they uploaded, please note this is done by HTTP_REFERER checking not all http servers or browsers support this however is more widely supported than Apache's mod_rewrite. Should you wish to stop deep linking then upload a image called badcontent.gif to your forums directory.

Further more instructions are provided in how to get this hack to work if you are using vBulletin's standard sig editor or a advanced sig editor hack.

and it says that this hack will only work on phpversion: 4.0.6

Is that a precaution or is there any chance that it will work with phpversion: 4.0.5????

Actually the readme states:
PHP 4 >= 4.1.0
PHP 4 4.0.6+Upload Patch can used if the installation script is modifed.

So no 4.0.5 can not be used, and neither is 4.0.6 recommended.

where is the upload patch located?

php.net under "File Uploads Security Fix". This only applies to PHP 4.0.6.

Naturally to apply the fix you require 4.0.6 installed from source and the pre-requisit privalages on the server.

Additionally using this hack with PHP 4.0.6 without or even with the mentioned patch is completely at your own risk.

All current versions PHP (e.g. 4.2.3) are not affected and do not require this.

so php 4.0.5 with the security patch cannot be used...

what problems cud this cause on a php with version 4.0.5 or 4.0.6 anyway?

Firstly:
http://security.e-matters.de/advisories/012002.html

Secondly:
This hack has not been tested on 4.0.5

Finnally:
The installer won't work on 4.0.6, it requires functions present in 4.1.0 or newer. To get round this you need to manually alter the installer to work on 4.0.6.
No help or support in doing this will be provided.
