Overview
tar is a full-featured Tar for Node.js.
Affected versions of this package are vulnerable to Interpretation Conflict due to improper handling of PAX extended header size overrides in intermediary metadata headers. An attacker can cause inconsistent archive parsing results between different tar implementations by crafting a malicious tar archive that desynchronizes the parser's interpretation, potentially hiding files from scanners or extractors that rely on different tools.
