Short explanation
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, leading to memory corruption and crashes.
Attackers can cause memory corruption and application crashes using a crafted .las file; the CVSS base score varies between 6.1 and 6.9 depending on the source.
What should be done?
- Follow vendor advisories as patch status is currently unknown
- Avoid processing untrusted .las files
- Monitor affected tools for updates

Show the technical text from the sources
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.
