Incorrect Permission Assignment for Critical Resource in NPM

Quick fix

GHSA-ph34-pc88-72gc — npm: upgrade to the fixed version with the command below.

npm install npm@5.7.1

Details

An issue was discovered in an npm 5.7.0 2018-02-21 pre-release (marked as "next: 5.7.0" and therefore automatically installed by an "npm upgrade -g npm" command, and also announced in the vendor's blog without mention of pre-release status). It might allow local users to bypass intended filesystem access restrictions because ownerships of /etc and /usr directories are being changed unexpectedly, related to a "correctMkdir" issue.
