A flaw was found in node-tar, a library for manipulating tar archives in Node.js. This vulnerability occurs when the library incorrectly converts specific archive path values into numbers, leading to an error during subsequent path processing. An attacker could exploit this to cause the application using node-tar to crash, resulting in a denial of service.

node-tar is a tar archive manipulation library for Node.js. Prior to 7.5.18, node-tar coerces all-digit PAX path and linkpath values in src/pax.ts to JavaScript numbers, causing downstream path handling such as normalizeWindowsPath(entry.path).split('/') to throw an uncaught TypeError. This issue is fixed in version 7.5.18.
