Fixes a regression introduced in nodejs@4ae320f The posix version of normalize should not treat backslash as a path separator. Fixes: nodejs#19519

Can braces be added for the if and else here if we start having multi-line conditional bodies?

CI: https://ci.nodejs.org/job/node-test-pull-request/13821/

Should we fast track this patch / a 9.9.1 or can this wait for next week?

It's difficult to estimate the impact (I suppose backslashes are not common in unixes paths). It can probably wait and land with the next security release.

This is a security release. All Node.js users should consult the security release summary at: https://nodejs.org/en/blog/vulnerability/march-2018-security-releases/ for details on patched vulnerabilities. Fixes for the following CVEs are included in this release: * CVE-2018-7158 * CVE-2018-7159 * CVE-2018-7160 Notable changes: * Upgrade to OpenSSL 1.0.2o: Does not contain any security fixes that are known to impact Node.js. * **Fix for inspector DNS rebinding vulnerability (CVE-2018-7160)**: A malicious website could use a DNS rebinding attack to trick a web browser to bypass same-origin-policy checks and allow HTTP connections to localhost or to hosts on the local network, potentially to an open inspector port as a debugger, therefore gaining full code execution access. The inspector now only allows connections that have a browser `Host` value of `localhost` or `localhost6`. * **Fix for `'path'` module regular expression denial of service (CVE-2018-7158)**: A regular expression used for parsing POSIX an Windows paths could be used to cause a denial of service if an attacker were able to have a specially crafted path string passed through one of the impacted `'path'` module functions. * **Reject spaces in HTTP `Content-Length` header values (CVE-2018-7159)**: The Node.js HTTP parser allowed for spaces inside `Content-Length` header values. Such values now lead to rejected connections in the same way as non-numeric values. * **Update root certificates**: 5 additional root certificates have been added to the Node.js binary and 30 have been removed. * cluster: - Add support for `NODE_OPTIONS="--inspect"` (Sameer Srivastava) #19165 * crypto: - Expose the public key of a certificate (Hannes Magnusson) #17690 * n-api: - Add `napi_fatal_exception` to trigger an `uncaughtException` in JavaScript (Mathias Buus) #19337 * path: - Fix regression in `posix.normalize` (Michaël Zasso) #19520 * stream: - Improve stream creation performance (Brian White) #19401 * Added new collaborators - [BethGriggs](https://github.com/BethGriggs) Beth Griggs PR-URL: https://github.com/nodejs-private/node-private/pull/111
