Statement:

This vulnerability does not affect the php55-php-pecl-imagick package shipped in OpenShift Container Platform 3.4 as it does not contain the vulnerable code. The vulnerable source file, imagickkernel_class.c, was added to php-imagick in version 3.3.0. OpenShift Container Platform ships version 3.1.2 and does not contain this source file.
