The graphite2::TtfUtil::CmapSubtable12Lookup 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, a different vulnerability than CVE-2016-2801.

Security readout for executives and security teams

A crafted Graphite smart font could make vulnerable Graphite 2 font-processing code read beyond a buffer. In affected Firefox and Firefox ESR versions, this could crash the browser and may have other unspecified impact. The main business concern is legacy browser or operating-system exposure to untrusted font content. Exposure is most likely on endpoints, server-side renderers, or applications running Graphite 2 before 1.3.6, Firefox before 45.0, or Firefox ESR before 38.7. The provided affected-product metadata is incomplete, so package and application inventory is needed. Prioritize as a legacy exposure cleanup item, especially where untrusted fonts, documents, or web content are processed. It is not KEV-listed in the supplied data, but remote crash risk in browsers and rendering stacks justifies patch verification. Mitigation focus: Upgrade Graphite 2 to version 1.3.6 or later where vendor packages are available.; Upgrade Firefox to 45.0 or later and Firefox ESR to 38.7 or later.; Apply relevant Mozilla, Ubuntu, Debian, SUSE, openSUSE, or Oracle security updates..
