CVSS 3.0
8.8 highCVSS:3.0/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:HCVE-2016-1521
High (8.8). EPSS 4.1% chance of exploitation in the next 30 days.
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.
