How to fix?

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 ip2long function in PHP 5.1.4 and earlier may incorrectly validate an arbitrary string and return a valid network IP address, which allows remote attackers to obtain network information and facilitate other attacks, as demonstrated using SQL injection in the X-FORWARDED-FOR Header in index.php in MiniBB 2.0. NOTE: it could be argued that the ip2long behavior represents a risk for security-relevant issues in a way that is similar to strcpy's role in buffer overflows, in which case this would be a class of implementation bugs that would require separate CVE items for each PHP application that uses ip2long in a security-relevant manner.
