How to fix?

There is no fixed version for Centos:6 nscd.

NVD Description

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

The PTR_MANGLE implementation in the GNU C Library (aka glibc or libc6) 2.4, 2.17, and earlier, and Embedded GLIBC (EGLIBC) does not initialize the random value for the pointer guard, which makes it easier for context-dependent attackers to control execution flow by leveraging a buffer-overflow vulnerability in an application and using the known zero value pointer guard to calculate a pointer address.
