NVD Description

Note: Versions mentioned in the description apply only to the upstream php-tidy package and not the php-tidy package as distributed by RHEL. See How to fix? for RHEL:6 relevant fixed versions and status.

The php_wddx_pop_element function in ext/wddx/wddx.c in PHP 7.0.x before 7.0.15 and 7.1.x before 7.1.1 allows remote attackers to cause a denial of service (NULL pointer dereference and application crash) via an inapplicable class name in a wddxPacket XML document, leading to mishandling in a wddx_deserialize call.
