CVE-2007-1700  (opens in a new tab)
CWE-94  (opens in a new tab)

How to fix?

Upgrade php to version 4.4.5, 5.2.1 or higher.

Overview

Affected versions of this package are vulnerable to Arbitrary Code Execution. The session extension in PHP 4 before 4.4.5, and PHP 5 before 5.2.1, calculates the reference count for the session variables without considering the internal pointer from the session globals, which allows context-dependent attackers 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.
