SIF is an open source implementation of the Singularity Container Image Format. The siftool new command and func siftool.New() produce predictable UUID identifiers due to insecure randomness in the version of the github.com/satori/go.uuid module used as a dependency. A patch is available in version >= v1.2.3 of the module. Users are encouraged to upgrade. As a workaround, users passing CreateInfo struct should ensure the ID field is generated using a version of github.com/satori/go.uuid that is not vulnerable to this issue.
