| Package | Affected versions | Patched versions |
|---|---|---|
| php | = 4.4.0= 5.2.0 |
PHP 5.2.0 and 4.4 allows local users to bypass safe_mode and open_basedir restrictions via a malicious path and a null byte before a ";" in a session_save_path argument, followed by an allowed path, which causes a parsing inconsistency in which PHP validates the allowed path but sets session.save_path to the malicious path.
