The Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the UTSA-2025-993343 advisory.A vulnerability has been identified in the libarchive library. This flaw involves an integer overflow that can be triggered when processing a Web Archive (WARC) file that claims to have more than INT64_MAX - 4 content bytes.

This bug affects libarchive versions prior to 3.8.0.
