How to fix?

Upgrade Centos:7 php-intl to version 0:5.4.16-36.el7_1 or higher.

NVD Description

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

PHP before 5.4.40, 5.5.x before 5.5.24, and 5.6.x before 5.6.8 does not ensure that pathnames lack %00 sequences, which might allow remote attackers to read or write to arbitrary files via crafted input to an application that calls (1) a DOMDocument load method, (2) the xmlwriter_open_uri function, (3) the finfo_file function, or (4) the hash_hmac_file function, as demonstrated by a filename\0.xml attack that bypasses an intended configuration in which client users may read only .xml files.
