How to fix?

There is no fixed version for RHEL:7 php-pdo.

NVD Description

Note: Versions mentioned in the description apply only to the upstream php-pdo package and not the php-pdo package as distributed by RHEL. See How to fix? for RHEL:7 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 accepts a negative integer for the scale argument, which allows remote attackers to cause a denial of service or possibly have unspecified other impact via a crafted call.
