There is no fixed version for Ubuntu:14.04 harfbuzz.

NVD Description

Note: Versions mentioned in the description apply only to the upstream harfbuzz package and not the harfbuzz package as distributed by Ubuntu. See How to fix? for Ubuntu:14.04 relevant fixed versions and status.

HarfBuzz before 1.0.4 allows remote attackers to cause a denial of service (invalid read of two bytes and application crash) because of GPOS and GSUB table mishandling, related to hb-ot-layout-gpos-table.hh, hb-ot-layout-gsub-table.hh, and hb-ot-layout-gsubgpos-private.hh.
