Summary

adm-zip before 0.6.1 contains a denial of service vulnerability that allows unauthenticated attackers to crash the Node.js process via a malformed ZIP file, because inflateAsync in methods/inflater.js lacks a zlib stream error listener. Attackers can supply a ZIP with corrupted DEFLATE data processed by readFileAsync, readAsTextAsync, extractAllToAsync, or getDataAsync, triggering an uncatchable exception that terminates all in-flight requests.

Patch / fix

  • npm adm-zip 0.6.1
  • cthackers adm-zip 0.6.1
