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.
