Attackers can craft a .las file with a LASSchema variable length record whose schema exceeds 65535 bytes, so tools like lasinfo, las2las, or las2txt write attacker-controlled bytes past the heap buffer, causing memory corruption and crashes.","state":0,"publishedAt":"2026-10-18T12:19:49.627+00:00","modifiedAt":"2026-10-22T02:19:48.617+00:00","affected":[{"ecosystem":"https://github.com/libLAS/libLAS","name":"libLAS","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"libLAS\",\n                    \"product\": \"libLAS\",\n                    \"defaultStatus\": \"unaffected\",\n                    \"versions\": [\n                        {\n                            \"version\": \"0\",\n                            \"lessThanOrEqual\": \"1.8.1\",\n                            \"status\": \"affected\",\n                            \"versionType\": \"custom\"\n                        }\n                    ],\n                    \"collectionURL\": \"https://github.com/libLAS/libLAS\",\n                    \"packageURL\": \"pkg:github/libLAS/libLAS\",\n                    \"repo\": \"https://github.com/libLAS/libLAS\"\n                }"}],"metrics":[{"system":"CVSS 4.0","vector":"CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:P/VC:N/VI:L/VA:H/SC:N/SI:N/SA:N","score":6.9,"severity":"MEDIUM"},{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:N/I:L/A:H","score":6.1,"severity":"MEDIUM"}],"references":["https://hackmd.io/@haindpwn/liblas-record-length-truncation-heap-overflow","https://github.com/libLAS/libLAS/blob/1.8.1/src/detail/reader/reader.cpp","https://github.com/libLAS/libLAS/blob/1.8.1/src/header.cpp","https://www.vulncheck.com/advisories/liblas-through-1.8.1-heap-out-of-bounds-write-via-lasschema-vlr"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-112059","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-112059","identifiers":["CVE-2026-112059"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
