description

adm-zip versions before 0.6.1 can terminate a Node.js process when asynchronous ZIP decompression handles malformed compressed data. An unauthenticated attacker can cause a denial of service if an application accepts untrusted ZIP archives and processes them through affected async APIs.

mitigation

Upgrade npm package adm-zip to version 0.6.1 or later. Until upgraded, avoid processing untrusted ZIP archives with adm-zip asynchronous decompression APIs.

fixed in 0.6.1
