How to fix?

Upgrade Centos:6 libtasn1 to version 0:2.3-6.el6_5 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream libtasn1 package and not the libtasn1 package as distributed by Centos. See How to fix? for Centos:6 relevant fixed versions and status.

The (1) asn1_read_value_type and (2) asn1_read_value functions in GNU Libtasn1 before 3.6 allows context-dependent attackers to cause a denial of service (NULL pointer dereference and crash) via a NULL value in an ivalue argument.
