A flaw was found in node-tar, a tar archive manipulation library for Node.js. This vulnerability allows a remote attacker to craft a small gzip bomb, which, when processed, can lead to the exhaustion of disk space and CPU resources. This occurs because node-tar does not enforce strict limits on the total decompressed data, the number of entries, or the decompression ratio during extraction and parsing. The primary impact is a Denial of Service (DoS), making the affected system or application unavailable.
