{"id":"CVE-2026-110603","summary":"LASzip through 3.5.0 Invalid Free via Truncated VLR Header in laszip_read_header","details":"LASzip through 3.5.0 contains an invalid free vulnerability in laszip_read_header() that allows attackers to free uninitialized heap pointers via truncated variable length record data. Attackers can supply a crafted LAS/LAZ file with an inflated VLR count that, when opened and destroyed through the C API, crashes the process and corrupts the heap.","modified":"2026-10-15T02:47:33.543637636Z","published":"2026-10-14T14:16:44.360Z","database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/110xxx/CVE-2026-110603.json","cna_assigner":"VulnCheck","cwe_ids":["CWE-824"]},"references":[{"type":"WEB","url":"https://github.com"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/110xxx/CVE-2026-110603.json"},{"type":"PACKAGE","url":"https://github.com/LASzip/LASzip"},{"type":"ARTICLE","url":"https://github.com/LASzip/LASzip/blob/3.5.0/src/laszip_dll.cpp#L3967-L3995"},{"type":"ARTICLE","url":"https://github.com/LASzip/LASzip/blob/3.5.0/src/laszip_dll.cpp#L497-L511"},{"type":"FIX","url":"https://github.com/LASzip/LASzip/commit/c9bfd3e68d65c84d513a2286ae06cbbe17afda02"},{"type":"ADVISORY","url":"https://hackmd.io/@haind-pwn/laszip-vlr-uninitialized-free"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-110603"},{"type":"ADVISORY","url":"https://www.vulncheck.com/advisories/laszip-through-3.5.0-invalid-free-via-truncated-vlr-header-in-laszip-read-header"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/laszip/laszip","events":[{"introduced":"0"},{"last_affected":"fa089bd8b2b4ca5631e199d257374c32a125f73f"}],"database_specific":{"extracted_events":[{"introduced":"0"},{"last_affected":"3.5.0"}],"source":"AFFECTED_FIELD"}}],"versions":["3.5.0","3.4.3","3.4.1","3.4.0","3.3.1","3.3.0","3.2.9","3.2.8","3.2.2","3.2.1","3.2.0","3.1.1","3.1.0","v2.2.0","2.0.2","2.0.1","2.0.0","1.2.0","1.0.1"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-110603.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:L/AC:L/AT:P/PR:N/UI:P/VC:N/VI:H/VA:H/SC:N/SI:N/SA:N"}]}
