The graphite2::TtfUtil::CmapSubtable4NextCodepoint 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

This flaw is in Graphite 2 font handling, including old Firefox releases. A malicious Graphite smart font could crash affected software and may have other unspecified effects. The strongest business concern is exposure through outdated browsers or Linux packages that process untrusted fonts. Exposure is most likely on legacy systems running Graphite 2 before 1.3.6, Firefox before 45.0, or Firefox ESR 38.x before 38.7, especially where untrusted fonts or web content may be processed. Treat this as a legacy exposure cleanup item unless affected software is internet-facing or still used for browsing untrusted content. Prioritize patching old Firefox and Graphite 2 packages on supported platforms. Mitigation focus: Upgrade Graphite 2 to version 1.3.6 or later where vendor packages provide it.; Upgrade Firefox to 45.0 or later, and Firefox ESR to 38.7 or later.; Apply relevant Linux distribution security updates from SUSE, Ubuntu, Debian, or your vendor..
