Affected: Homebrew: node

Affected versions of `npm` use predictable temporary file names during archive unpacking. If an attacker can create a symbolic link at the location of one of these temporary file names, the attacker can arbitrarily write to any file that the user which owns the `npm` process has permission to write to, potentially resulting in local privilege escalation.

## Recommendation

Update to version 1.3.3 or later.

lib/npm.js in Node Packaged Modules (npm) before 1.3.3 allows local users to overwrite arbitrary files via a symlink attack on temporary files with predictable names that are created when unpacking archives.
