There is no fixed version for Centos:6 php-embedded.

NVD Description

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

The bcpowmod function in ext/bcmath/bcmath.c in PHP before 5.5.35, 5.6.x before 5.6.21, and 7.x before 7.0.6 modifies certain data structures without considering whether they are copies of the zero, one, or two global variable, which allows remote attackers to cause a denial of service or possibly have unspecified other impact via a crafted call.
