NVD Description

Note: Versions mentioned in the description apply only to the upstream rh-php70-php-opcache package and not the rh-php70-php-opcache package as distributed by RHEL. See How to fix? for RHEL:7 relevant fixed versions and status.

ext/spl/spl_array.c in PHP before 5.6.26 and 7.x before 7.0.11 proceeds with SplArray unserialization without validating a return value and data type, which allows remote attackers to cause a denial of service or possibly have unspecified other impact via crafted serialized data.
