+## _(Update 18-December-2019)_ Releases available
+
+These releases update npm to v6.13.4 to address three vulnerabilities described below.
+
+All current release lines were affected.
+
+At this time, CVEs have been requested by npm, Inc. and are pending review. See https://twitter.com/ahmadnassri/status/1205132161961123841 for more information.
+
+### Global `node_modules` Binary Overwrite
+
+Versions of the npm CLI prior to 6.13.4 are vulnerable to a Global `node_modules` Binary Overwrite. It fails to prevent existing globally-installed binaries to be overwritten by other package installations.
+
+For example, if a package was installed globally and created a `serve` binary, any subsequent installs of packages that also create a `serve` binary would overwrite the first binary. This will not overwrite system binaries but only binaries put into the global `node_modules` directory.
+
+This behavior is still allowed in local installations and also through install scripts. This vulnerability bypasses a user using the `--ignore-scripts` install option.
+
+* https://www.npmjs.com/advisories/1437
+
+### Symlink reference outside of `node_modules`
+
+Versions of the npm CLI prior to 6.13.3 are vulnerable to a symlink reference outside of `node_modules`. It is possible for packages to create symlinks to files outside of the `node_modules` folder through the `bin` field upon installation. A properly constructed entry in the package.json `bin` field would allow a package publisher to create a symlink pointing to arbitrary files on a user’s system when the package is installed. Only files accessible by the user running the `npm install` are affected.
+
+This behavior is still possible through install scripts. This vulnerability bypasses a user using the `--ignore-scripts` install option.
+
+* https://www.npmjs.com/advisories/1436
+
+### Arbitrary File Write
+
+Versions of the npm CLI prior to 6.13.3 are vulnerable to an Arbitrary File Write. It fails to prevent access to folders outside of the intended `node_modules` folder through the `bin` field. A properly constructed entry in the package.json `bin` field would allow a package publisher to modify and/or gain access to arbitrary files on a user’s system when the package is installed. It is only possible to affect files that the user running `npm install` has access to.
+
+This behavior is still possible through install scripts. This vulnerability bypasses a user using the `--ignore-scripts` install option.
