Descriptions

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.

SIF es una implementación de código abierto del Singularity Container Image Format. El comando "siftool new" y func siftool.New() producen identificadores UUID predecibles debido a una aleatoriedad no segura en la versión del módulo `github.com/satori/go.uuid" usado como dependencia. Un parche disponible en la versión posteriores a v1.2.3 incluyéndo la del módulo. Los usuarios están decididos a actualizar. Como solución alternativa, los usuarios que pasen la estructura CreateInfo deben asegurarse de que el campo "ID" se genere utilizando una versión de "github.com/satori/go.uuid" que no es vulnerable a este problema
