PHP 'error_log' Safe Mode Restriction-Bypass Vulnerability

PHP is prone to a 'safe_mode' restriction-bypass vulnerability. Successful exploits could allow an attacker to write files in unauthorized locations.

This vulnerability would be an issue in shared-hosting configurations where multiple users can create and execute arbitrary PHP script code, with the 'safe_mode' restrictions assumed to isolate the users from each other.

Versions prior to PHP 5.2.8 are vulnerable.
