How to fix?

Upgrade Ubuntu:14.04 libtasn1-6 to version 3.4-3ubuntu0.3 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 _asn1_extract_der_octet function in lib/decoding.c in GNU Libtasn1 before 4.5 allows remote attackers to cause a denial of service (out-of-bounds heap read) via a crafted certificate.
