{"id":"UBUNTU-CVE-2026-110603","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":"2026-10-17T12:59:52.587649217Z","published":"2026-10-15T00:00:00Z","upstream":["CVE-2026-110603"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2026-110603"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2026-110603"},{"type":"REPORT","url":"https://github.com/LASzip/LASzip/blob/3.5.0/src/laszip_dll.cpp#L3967-L3995"},{"type":"REPORT","url":"https://github.com/LASzip/LASzip/blob/3.5.0/src/laszip_dll.cpp#L497-L511"},{"type":"REPORT","url":"https://github.com/LASzip/LASzip/commit/c9bfd3e68d65c84d513a2286ae06cbbe17afda02"},{"type":"REPORT","url":"https://hackmd.io/@haind-pwn/laszip-vlr-uninitialized-free"},{"type":"REPORT","url":"https://www.vulncheck.com/advisories/laszip-through-3.5.0-invalid-free-via-truncated-vlr-header-in-laszip-read-header"}],"affected":[{"package":{"name":"laszip","ecosystem":"Ubuntu:20.04:LTS","purl":"pkg:deb/ubuntu/laszip?arch=source&distro=focal"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["3.4.1-2","3.4.3-1","3.4.3-1build1"],"ecosystem_specific":{"binaries":[{"binary_name":"liblaszip-api8","binary_version":"3.4.3-1build1"},{"binary_name":"liblaszip8","binary_version":"3.4.3-1build1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-110603.json"}},{"package":{"name":"laszip","ecosystem":"Ubuntu:22.04:LTS","purl":"pkg:deb/ubuntu/laszip?arch=source&distro=jammy"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["3.4.3-2"],"ecosystem_specific":{"binaries":[{"binary_name":"liblaszip-api8","binary_version":"3.4.3-2"},{"binary_version":"3.4.3-2","binary_name":"liblaszip8"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-110603.json"}},{"package":{"name":"laszip","ecosystem":"Ubuntu:24.04:LTS","purl":"pkg:deb/ubuntu/laszip?arch=source&distro=noble"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["3.5.0-1"],"ecosystem_specific":{"binaries":[{"binary_name":"liblaszip-api8","binary_version":"3.5.0-1"},{"binary_name":"liblaszip8","binary_version":"3.5.0-1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-110603.json"}},{"package":{"name":"laszip","ecosystem":"Ubuntu:26.10","purl":"pkg:deb/ubuntu/laszip?arch=source&distro=stonking"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["3.5.0+really3.5.0-1"],"ecosystem_specific":{"binaries":[{"binary_name":"liblaszip-api8","binary_version":"3.5.0+really3.5.0-1"},{"binary_version":"3.5.0+really3.5.0-1","binary_name":"liblaszip8"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-110603.json"}},{"package":{"name":"laszip","ecosystem":"Ubuntu:26.04:LTS","purl":"pkg:deb/ubuntu/laszip?arch=source&distro=resolute"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["3.5.0-2","3.5.0+really3.5.0-1"],"ecosystem_specific":{"binaries":[{"binary_name":"liblaszip-api8","binary_version":"3.5.0+really3.5.0-1"},{"binary_version":"3.5.0+really3.5.0-1","binary_name":"liblaszip8"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-110603.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:H/PR:N/UI:R/S:U/C:N/I:H/A:H"},{"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"},{"type":"Ubuntu","score":"medium"}]}
