Description
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.
