Updated php-ZendFramework/php-ZendFramework2 packages fixe security vulnerabilities

Zend Framework contained several instances where it was using incorrect permissions masks, which could lead to local privilege escalation issues (CVE-2015-5723). The PDO adapters of Zend Framework 1 do not filter null bytes values in SQL statements. A PDO adapter can treat null bytes in a query as a string terminator, allowing an attacker to add arbitrary SQL following a null byte, and thus create a SQL injection (ZF2015-08). Note that the ZF2015-08 issue did not affect Zend Framework 2.
