CyberRota Analysis

AI-Generated

The node-tar library for Node.js is vulnerable to an issue where the tar.replace function can accept a checksum-valid tar header with a negative base-256 encoded entry size, leading to denial of service as the archive scanner gets stuck in an infinite loop. This vulnerability impacts applications relying on affected versions prior to 7.5.18, and organizations using node-tar should prioritize upgrading to version 7.5.18 or later to mitigate potential service disruptions.
