| Package | Affected versions | Patched versions |
|---|---|---|
| bundler | ≥ 1.14.0, < 2.1.0 | 2.1.0 |
| bundler | < 2.1.0 | 2.1.0 |
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.
