CVE-2007-1484  (opens in a new tab)
CWE-400  (opens in a new tab)

How to fix?

Upgrade php to version 4.4.7, 5.2.2 or higher.

Overview

Affected versions of this package are vulnerable to Denial of Service (DoS). The array_user_key_compare function in PHP 4.4.6 and earlier, and 5.x up to 5.2.1, makes erroneous calls to zval_dtor, which triggers memory corruption and allows local users to bypass safe_mode and execute arbitrary code via a certain unset operation after array_user_key_compare has been called.
