NVD Description

Note: Versions mentioned in the description apply only to the upstream laszip package and not the laszip package as distributed by Echo. See How to fix? for Echo:latest relevant fixed versions and status.

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.
