This CVE was assigned to "Update harfbuzz to 1.0.6" in chromium browser. (As referenced by the comment #0 above). When investigating this issue it seems all the issues fixed in 1.0.5 and subsequent 1.0.6 are linked to their fuzzing initiative as obvious from https://github.com/behdad/harfbuzz/issues/139.

Several flaws were fixed, which include:

Several heap-based buffer overflows at:
