Description Vladimir Vasilev 2026-10-15 18:08:25 UTC

Disclaimer: Community trackers are created by Red Hat Product Security team on a best effort basis. Package maintainers are required to ascertain if the flaw indeed affects their package, before starting the update process.

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.
