Description Adam Mariš 2017-05-30 06:01:08 EDT 
The i_zval_ptr_dtor function in Zend/zend_variables.h in PHP 7.1.5 allows attackers to cause a denial of service (memory consumption and application crash) or possibly have unspecified other impact by triggering crafted operations on array data structures.

Affects: fedora-all [bug 1456751]
Comment 2 Huzaifa S. Sidhpurwala 2017-07-03 03:35:32 EDT 
Analysis:

This seems to be more like a memory exhaustion which is caused by malicious PHP script. I dont see this as being triggerable by a malicious PHP application user.
