NVD Description

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

The php_wddx_push_element function in ext/wddx/wddx.c in PHP before 5.6.26 and 7.x before 7.0.11 allows remote attackers to cause a denial of service (invalid pointer access and out-of-bounds read) or possibly have unspecified other impact via an incorrect boolean element in a wddxPacket XML document, leading to mishandling in a wddx_deserialize call.
