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.

GHSA-w8wr-v893-vjvp — node-tar: Process crash via PAX numeric path type confusion

Affected: npm: tar

### Summary

A crafted 2.5KB tar archive crashes any Node.js process that extracts it. The PAX header parser coerces all-digit path values to JavaScript numbers, which causes an uncaught TypeError when downstream code calls `.split('/')` on the numeric value. Error handlers and `strict: false` cannot intercept the crash.

### Details

In `pax.ts` line 180, `parseKV` converts PAX values matching `/^[0-9]+$/` to numbers via `+v`. This applies to all fields including `path` and `linkpath`. When a PAX header sets `path` to an all-digit string like `"12345"`, the value becomes the number `12345`.

This number flows through Header -> ReadEntry -> Unpack.CHECKPATH, where `normalizeWindowsPath(entry.path).split('/')` throws a TypeError because numbers don't have `.split()`.

The throw is synchronous during event emission and bypasses all error handling: - `strict: false` does not help - `'error'` event handlers do not catch it - `'warn'` handlers do not catch it - The TypeError propagates through the event emitter stack as an uncaughtException

Directory, SymbolicLink, and Link type entries reach CHECKPATH and crash. File type entries crash earlier in Header constructor at `this.path.slice(-1)`, but that throw is caught and emitted as a warning only.

### PoC

Create a tar archive with a PAX extended header containing an all-digit path:

``` PAX header body: "18 path=12345\n" Entry type: Directory (type '5') ```

Extract it: ```js const tar = require('tar');

// All of these crash w…
