New CVE NOT AVAILABLE CWE-770  (opens in a new tab)

How to fix?

Upgrade adm-zip to version 0.6.1 or higher.

Overview

adm-zip is a JavaScript implementation for zip data compression for NodeJS.

Affected versions of this package are vulnerable to Allocation of Resources Without Limits or Throttling via the async decompression path in methods/inflater.js, where the maxOutputLength cap enforced by zlib's sync API is not applied to the streaming (async) path. An attacker can supply a ZIP entry whose declared uncompressed size is small but whose compressed payload expands arbitrarily, causing unbounded memory growth and crashing the host process.
