Overview
adm-zip is a JavaScript implementation for zip data compression for NodeJS.
Affected versions of this package are vulnerable to Uncaught Exception via inflateAsync in methods/inflater.js when processing a ZIP entry containing malformed DEFLATE data. The zlib.createInflateRaw stream emits an error event (e.g. Z_DATA_ERROR) that has no registered listener, causing Node.js to re-throw it as an uncaught exception on a later tick and crash the host process.
