{"id":"CVE-2026-112059","summary":"libLAS through 1.8.1 Heap Out-of-Bounds Write via LASSchema VLR","details":"libLAS through 1.8.1 contains a heap out-of-bounds write vulnerability in the point record reader caused by truncating the schema byte size to 16 bits when sizing the point buffer. 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.","modified":"2026-10-21T02:55:50.637668066Z","published":"2026-10-18T12:19:49.627Z","database_specific":{"cna_assigner":"VulnCheck","cwe_ids":["CWE-787"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/112xxx/CVE-2026-112059.json"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/112xxx/CVE-2026-112059.json"},{"type":"PACKAGE","url":"https://github.com/libLAS/libLAS"},{"type":"ARTICLE","url":"https://github.com/libLAS/libLAS/blob/1.8.1/src/detail/reader/reader.cpp"},{"type":"ARTICLE","url":"https://github.com/libLAS/libLAS/blob/1.8.1/src/header.cpp"},{"type":"ADVISORY","url":"https://hackmd.io/@haindpwn/liblas-record-length-truncation-heap-overflow"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-112059"},{"type":"ADVISORY","url":"https://www.vulncheck.com/advisories/liblas-through-1.8.1-heap-out-of-bounds-write-via-lasschema-vlr"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/liblas/liblas","events":[{"introduced":"0"},{"last_affected":"ca742e3bf367b4c30beb6cd3e39aa32852b411ec"}],"database_specific":{"extracted_events":[{"source":"AFFECTED_FIELD","strategy":"StandardRange","range":[{"introduced":"0"},{"last_affected":"1.8.1"}]}]}}],"versions":["1.8.1","1.8.0","1.7.1b2","1.7.1b1","1.7.0","1.2.0","1.2.0b1","1.0.0","1.0.0b2","1.0.0b1","0.9.7","0.9.6","0.9.5","0.9.4","0.9.2","0.9.1","0.9.0","progress-20071229","original"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-112059.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V4","score":"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"}]}
