PHP Multiple Functions 'safe_mode_exec_dir' and 'open_basedir' Restriction Bypass Vulnerabilities

PHP is prone to 'safe_mode_exec_dir' and 'open_basedir' restriction-bypass vulnerabilities. Successful exploits could allow an attacker to execute arbitrary code.

These vulnerabilities would be an issue in shared-hosting configurations where multiple users can create and execute arbitrary PHP script code; in such cases, the 'safe_mode' and 'open_basedir' restrictions are expected to isolate users from each other.

PHP 5.2.5 is vulnerable; other versions may also be affected.
