PHP .Htaccess 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 write files in unauthorized locations.

These vulnerabilities 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.

This issue is reported to affect PHP 5.2.3 and 4.4.7; previous versions may also be vulnerable.
