Summary

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.

Fencer Vulns keeps one entry per vulnerability: the CVE id wins, then GHSA, and records that alias each other are merged, except that two CVEs always keep separate entries. The same data is available as JSON.
