Bundler manages an application's dependencies through its entire life, across many machines, systematically and repeatably. Security Fix(es): 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.(CVE-2019-3881) An update for rubygem-bundler is now available for openEuler-20.03-LTS-SP2. openEuler Security has rated this update as having a security impact of high.
