CVE-2025-5916

A vulnerability has been identified in the libarchive library. This flaw involves an integer overflow that can be trigge

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. An attacker could craft a malicious WARC archive to induce this overflow, potentially leading to unpredictable program behavior, memory corruption, or a denial-of-service condition within applications that process such archives using libarchive.

This bug affects libarchive versions prior to 3.8.0.
