PHP cURL 'safe_mode' and 'open_basedir' Restriction-Bypass Vulnerability

PHP is prone to a 'safe_mode' and 'open_basedir' restriction-bypass vulnerability. Successful exploits could allow an attacker to access 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' and 'open_basedir' restrictions assumed to isolate the users from each other.

PHP 5.2.9 is vulnerable; other versions may also be affected.
