The session extension in PHP 4 prior to 4.4.5, and PHP 5 prior to 5.2.1, calculates the reference count for the session variables without considering the internal pointer from the session globals, which allows context-dependent malicious users to execute arbitrary code via a crafted string in the session_register after unsetting HTTP_SESSION_VARS and _SESSION, which destroys the session data Hashtable.
