How to fix?

There is no fixed version for Centos:7 libstdc++.

NVD Description

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

Heap/stack buffer overflow in the dlang_lname function in d-demangle.c in libiberty allows attackers to potentially cause a denial of service (segmentation fault and crash) via a crafted mangled symbol.
