CVE-2016-10583
closure-util downloads Resources over HTTP
Description
Affected versions of `closure-util` insecurely download an executable over an unencrypted HTTP connection. In scenarios where an attacker has a privileged network position, it is possible to intercept the response and replace the executable with a malicious one, resulting in code execution on the system running `closure-util`. ## Recommendation To mitigate this issue: 1. Install the package using npm's `--ignore-scripts` flag. 2. Navigate to the package directory, and open `default-config.json` in a text editor 3. Change the download URLs in the `compiler_url` and `library_url` to `https` equivalents 4. run `npm i` in the package directory.
