CVE-2016-2792: Buffer Overflow
First published: Sun Mar 13 2016(Updated: )
The graphite2::Slot::getAttr function in Slot.cpp in Graphite 2 before 1.3.6, as used in Mozilla Firefox before 45.0 and Firefox ESR 38.x before 38.7, allows remote attackers to cause a denial of service (buffer over-read) or possibly have unspecified other impact via a crafted Graphite smart font, a different vulnerability than CVE-2016-2800.
