Overview

npm is a package manager for JavaScript. Affected versions of the package are vulnerable to Symlink attack due to predictable tmp folder names, which were named /tmp/npm-$PID. An attacker waiting for a process named npm- to load could then go to the folder and arbitrarily change the files in the tmp folder.
