Heap-based buffer overflow in the graphite2::vm::Machine::Code::Code 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 or possibly have unspecified other impact via a crafted Graphite smart font.

Security readout for executives and security teams

CVE-2016-2796 is a memory corruption flaw in Graphite 2 font handling. A malicious Graphite smart font could crash affected software and may have allowed other unspecified impact. The clearest business risk is legacy browsers or Linux packages that still use Graphite 2 before 1.3.6 or affected Firefox versions. Exposure is most likely in legacy Linux desktop/server packages, embedded applications, or old browser installations that include Graphite 2 before 1.3.6 or Firefox before the fixed releases. Prioritize remediation where old browsers or document/font-rendering workflows process untrusted content. The issue is old, but unmanaged legacy endpoints or embedded systems may remain exposed. Mitigation focus: Upgrade Graphite 2 to version 1.3.6 or later.; Upgrade Firefox to 45.0 or later, and ESR to 38.7 or later.; Apply relevant vendor security updates from Mozilla and Linux distributors..
