Attackers can supply a crafted glTF or GLB file with large sparse indices to corrupt heap memory, crash applications, and potentially execute code when cgltf_validate() is not called.","cvssScore":7,"cvssSeverity":"HIGH","cvssVector":"CVSS:3.1/AV:L/AC:H/PR:N/UI:R/S:U/C:H/I:H/A:H","cwes":["CWE-787"],"vendors":[],"products":[],"references":[{"url":"https://github.com/jkuhlmann/cgltf","tags":[]},{"url":"https://github.com/jkuhlmann/cgltf/blob/360db1a95480fe102ae9c69b27c5d101167ff5ba/cgltf.h#L2436-L2441","tags":[]},{"url":"https://hackmd.io/@haindpwn/cgltf-accessor-unpack-floats-sparse-oob","tags":[]},{"url":"https://www.vulncheck.com/advisories/cgltf-through-1.15-heap-out-of-bounds-write-via-cgltf-accessor-unpack-floats","tags":[]}],"exploitRefs":[{"url":"https://github.com/jkuhlmann/cgltf","tags":[]},{"url":"https://github.com/jkuhlmann/cgltf/blob/360db1a95480fe102ae9c69b27c5d101167ff5ba/cgltf.h#L2436-L2441","tags":[]}],"hasPoc":true,"ai":null}
