Description

zend_hash_del_key_or_index in zend_hash.c in PHP before 4.4.3 and 5.x before 5.1.3 can cause zend_hash_del to delete the wrong element, which prevents a variable from being unset even when the PHP unset function is called, which might cause the variable's value to be used in security-relevant operations.

Solution(s)

  • php-upgrade-5_1_4
