Ref: https://nvd.nist.gov/vuln/detail/CVE-2017-8923
====================================================
Description

The zend_string_extend function in Zend/zend_string.h in PHP through 7.1.5 does
not prevent changes to string objects that result in a negative length, which
allows remote attackers to cause a denial of service (application crash) or
possibly have unspecified other impact by leveraging a script's use of .= with
a long string.
