Description Jon Moroney 2026-07-09 21:10:21 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.

node-tar is a tar archive manipulation library for Node.js. Prior to 7.5.19, node-tar does not enforce hard upper bounds on total decompressed data, entry counts, or decompression ratio in extraction and parsing paths such as src/extract.ts, allowing a small crafted gzip bomb to exhaust disk space and CPU. This issue is fixed in version 7.5.19.

nodejs20 is no longer supported by upstream, as it reached it's End-of-Life. We do not plan to release any more updates for it. Users are advised to migrate to a newer release (nodejs22, nodejs24).
