How to fix?

Upgrade Centos:6 libtasn1 to version 0:2.3-3.el6_2.1 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 asn1_get_length_der function in decoding.c in GNU Libtasn1 before 2.12, as used in GnuTLS before 3.0.16 and other products, does not properly handle certain large length values, which allows remote attackers to cause a denial of service (heap memory corruption and application crash) or possibly have unspecified other impact via a crafted ASN.1 structure.
