libLAS through 1.8.1 Heap Out-of-Bounds Write via LASSchema VLR

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.

liblas: memory leak may lead to DoS

libLAS 1.8.1 contains a memory leak vulnerability in /libLAS/apps/ts2las.cpp.

There is memory leak at liblas::Open (liblas/liblas.hpp) in libLAS 1.8.1.

There is a Segmentation fault triggered by illegal address access at liblas::SpatialReference::GetGTIF() (spatialreference.cpp) in libLAS 1.8.1 that will cause a denial of service.

There is a NULL pointer dereference at liblas::SpatialReference::GetGTIF() (spatialreference.cpp) in libLAS 1.8.1 that will cause a denial of service.

There is a heap-based buffer over-read at liblas::SpatialReference::GetGTIF() (spatialreference.cpp) in libLAS 1.8.1 that will cause a denial of service.
