From the recently disclosed Zend-mail remote code execution vulnerability:
Affected Zend Framework versions:
Zend Framework < 2.4.11 Remote Code Execution (CVE-2016-10034)
zend-mail < 2.4.11
zend-mail < 2.7.2
Should I be worried about this if Magento uses Zend Framework? Does Magento take proper precautions in sanitizing all types of email forms out-of-the-box?
