The graphite2::TtfUtil::CmapSubtable12Lookup function in TtfUtil.cpp 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-2016-2797.

Security readout for executives and security teams

CVE-2016-2801 is an old Graphite 2 font-parsing flaw. A malicious Graphite smart font could make affected software, including older Firefox releases, read past a buffer and crash. The sources mention possible unspecified other impact, but do not define it. Exposure is most likely on legacy Linux or desktop systems still running Graphite 2 before 1.3.6, Firefox before 45.0, or Firefox ESR before 38.7. Modern patched distributions should have limited exposure. Treat this as a legacy patching and exposure-control issue. It is not KEV-listed in the provided bundle, but affected browsers and font libraries process untrusted content, so unsupported systems should be remediated or isolated. Mitigation focus: Upgrade Graphite 2 to version 1.3.6 or later.; Update Firefox to 45.0 or later.; Update Firefox ESR 38.x to 38.7 or later..
