The graphite2::TtfUtil::CmapSubtable12NextCodepoint function 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.

Security readout for executives and security teams

CVE-2016-2794 is an old font-processing flaw in Graphite 2. A malicious Graphite smart font could crash affected software, including older Firefox releases, and sources leave open the possibility of other unspecified impact. The main business concern is legacy systems still rendering untrusted fonts with vulnerable Graphite 2 or bundled browser packages. Exposure is most likely on outdated Linux distributions, embedded systems, or legacy desktops running Graphite 2 before 1.3.6 or Firefox before the fixed versions. Current, fully patched systems are unlikely to remain exposed. Prioritize remediation for legacy endpoints and servers that process untrusted fonts or documents. This is not KEV-listed and active exploitation is not evidenced here, but remote crash potential in client software justifies routine patch validation. Mitigation focus: Upgrade Graphite 2 to version 1.3.6 or later.; Upgrade Firefox to 45.0 or later, and ESR 38.x to 38.7 or later.; Apply relevant SUSE, openSUSE, Ubuntu, Debian, Oracle, or Mozilla vendor updates..
