The graphite2::GlyphCache::glyph 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. A malicious Graphite smart font could crash affected software, and the public record leaves room for other unspecified impact. The clearest named exposure is older Firefox and Firefox ESR versions using vulnerable Graphite 2. Systems are most likely exposed through outdated Graphite 2 packages or applications bundling Graphite 2, especially Firefox before 45.0 and Firefox ESR before 38.7. Linux distributions issued advisories, so package-managed desktop and server software that renders untrusted fonts should be checked. Treat this as a patch hygiene issue with credible remote crash risk, not as an emergency exploitation event based on provided evidence. Prioritize browser and font-rendering software updates where untrusted content is opened. Mitigation focus: Upgrade Graphite 2 to version 1.3.6 or later.; Upgrade Firefox to 45.0 or later, and Firefox ESR to 38.7 or later.; Apply relevant Linux vendor security updates from your distribution..
