Insecure path handling in Bundler

Quick fix

GHSA-g98m-96g9-wfjq — bundler: upgrade to the fixed version with the command below.

bundle update bundler

Details

Bundler prior to 2.1.0 uses a predictable path in `/tmp/`, created with insecure permissions as a storage location for gems, if locations under the user's home directory are not available. If Bundler is used in a scenario where the user does not have a writable home directory, an attacker could place malicious code in this directory that would be later loaded and executed.
