CVE-2016-1521

Priority
Medium
Description
The directrun function in directmachine.cpp in Libgraphite in Graphite 2
1.2.4, as used in Mozilla Firefox before 43.0 and Firefox ESR 38.x before
38.6.1, does not validate a certain skip operation, which allows remote
attackers to execute arbitrary code, obtain sensitive information, or cause
a denial of service (out-of-bounds read and application crash) via a
crafted Graphite smart font.
