How to fix?

There is no fixed version for Centos:6 expat.

NVD Description

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

Expat, when used in a parser that has not called XML_SetHashSalt or passed it a seed of 0, makes it easier for context-dependent attackers to defeat cryptographic protection mechanisms via vectors involving use of the srand function.
