Last modified

CVE-2016-1522 is a vulnerability of currently unknown severity. Code.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 consider recursive load calls during a size check, which allows remote attackers to cause a denial of service (heap-based buffer overflow) or possibly execute arbitrary code via a crafted Graphite smart font.. EPSS estimates a 8.31% chance of exploitation in the next 30 days.
