How to fix?

Upgrade Ubuntu:14.04 libtasn1-6 to version 3.4-3ubuntu0.1 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream libtasn1-6 package and not the libtasn1-6 package as distributed by Ubuntu. See How to fix? for Ubuntu:14.04 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.
