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.","cvssScore":6.3,"cvssSeverity":"MEDIUM","cvssVector":"CVSS:3.1/AV:L/AC:H/PR:N/UI:R/S:U/C:N/I:H/A:H","cwes":["CWE-824"],"vendors":[],"products":[],"references":[{"url":"https://github.com/LASzip/LASzip/blob/3.5.0/src/laszip_dll.cpp#L3967-L3995","tags":[]},{"url":"https://github.com/LASzip/LASzip/blob/3.5.0/src/laszip_dll.cpp#L497-L511","tags":[]},{"url":"https://github.com/LASzip/LASzip/commit/c9bfd3e68d65c84d513a2286ae06cbbe17afda02","tags":[]},{"url":"https://hackmd.io/@haind-pwn/laszip-vlr-uninitialized-free","tags":[]},{"url":"https://www.vulncheck.com/advisories/laszip-through-3.5.0-invalid-free-via-truncated-vlr-header-in-laszip-read-header","tags":[]}],"exploitRefs":[{"url":"https://github.com/LASzip/LASzip/blob/3.5.0/src/laszip_dll.cpp#L3967-L3995","tags":[]},{"url":"https://github.com/LASzip/LASzip/blob/3.5.0/src/laszip_dll.cpp#L497-L511","tags":[]},{"url":"https://github.com/LASzip/LASzip/commit/c9bfd3e68d65c84d513a2286ae06cbbe17afda02","tags":[]}],"hasPoc":true,"ai":null}
