CyberRota Analysis
AI-GeneratedThe adm-zip library in JavaScript, prior to version 0.6.1, is vulnerable due to improper validation of the uncompressed size of ZIP entries, which can lead to excessive memory allocation and potential service-wide memory exhaustion when processing untrusted archives. This vulnerability poses a high risk to applications that utilize this library, particularly those that handle ZIP files from untrusted sources. Developers and organizations using adm-zip should prioritize upgrading to version 0.6.1 or later to mitigate this risk.

Original NVD Description
adm-zip is a JavaScript library for creating and extracting ZIP archives in Node.js. Prior to 0.6.1, getData() in zipEntry.js trusts an entry'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.
