Affected packages
• RubyGems bundler: >= 1.14.0, < 2.1.0 → fixed in 2.1.0
Description
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.
