Vulnerability Summary

The array_user_key_compare function in PHP 4.4.6 and previous versions, 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.
