CVE-2016-2052

Published: 25 January 2016

Multiple unspecified vulnerabilities in HarfBuzz before 1.0.6, as used in Google Chrome before 48.0.2564.82, allow attackers to cause a denial of service or possibly have other impact via crafted data, as demonstrated by a buffer over-read resulting from an inverted length check in hb-ot-font.cc, a different issue than CVE-2015-8947.
