Prior to 0.6.1, getData() in zipEntry.js trusts an entry&#39;s central-directory uncompressed size and allocates output memory before validating that value against the actual compressed data and decompression result. A small crafted ZIP can declare a multi-gigabyte uncompressed size, causing Buffer.alloc and decompression handling to commit excessive resident memory before CRC validation reports an error. Applications that read entries from untrusted archives can therefore be terminated by the operating system or suffer service-wide memory exhaustion. This issue is fixed in version 0.6.1.</p> <p>adm-zip is a JavaScript library for creating and extracting ZIP archives in Node.js.

A tiny crafted ZIP that declares a huge uncompressed size forces a multi-gigabyte allocation from a few bytes.</p> <p>### Impact On adm-zip 0.5.17 (latest), Node 24, a 105-byte ZIP with one stored entry declaring size = 1,774,399,200 makes `new AdmZip(buf).getEntries()[0].getData()` commit ~1.8 GB of resident memory in ~4.4 s before throwing `Error: ADM-ZIP: CRC32 checksum failed`, roughly 16 million times the input size. Because the buffer is committed before any validation, on a memory-constrained host (containers, serverless, small VMs) the allocation OOM-kills the process before the CRC check (uncatchable), and concurrent requests can exhaust memory even on larger hosts.
