CVE-2017-8923

Priority
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.
