Attackers can craft a .ftm, .dnm or 0CC/E-FamiTracker module with a 2A03 instrument note count above 120 to read past the noteMap array and crash Furnace when opened.","cvssScore":5.5,"cvssSeverity":"MEDIUM","cvssVector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:H","cwes":["CWE-125"],"vendors":[],"products":[],"references":[{"url":"https://github.com/tildearrow/furnace","tags":[]},{"url":"https://github.com/tildearrow/furnace/blob/v0.6.8.3/src/engine/fileOps/ftm.cpp#L981-L1017","tags":[]},{"url":"https://github.com/tildearrow/furnace/commit/c120c72391e3229fe258e5759f43427febcb8693","tags":[]},{"url":"https://github.com/tildearrow/furnace/issues/2966","tags":[]},{"url":"https://hackmd.io/@haindpwn/furnace-ftm-import-notemap-and-groove-subsong-oob","tags":[]},{"url":"https://www.vulncheck.com/advisories/furnace-through-0.6.8.3-out-of-bounds-read-via-famitracker-module-import","tags":[]}],"exploitRefs":[{"url":"https://github.com/tildearrow/furnace","tags":[]},{"url":"https://github.com/tildearrow/furnace/blob/v0.6.8.3/src/engine/fileOps/ftm.cpp#L981-L1017","tags":[]},{"url":"https://github.com/tildearrow/furnace/commit/c120c72391e3229fe258e5759f43427febcb8693","tags":[]},{"url":"https://github.com/tildearrow/furnace/issues/2966","tags":[]}],"hasPoc":true,"ai":null}
