CVE-2021-29499

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.

### Impact The `siftool new` command and [func siftool.New()](https://pkg.go.dev/github.com/sylabs/sif/pkg/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. ### Patches A patch is available in version >= v1.2.3 of the module. Users are encouraged to upgrade. The patch is commit https://github.com/sylabs/sif/commit/193962882122abf85ff5f5bcc86404933e71c07d ### Workarounds Users passing [CreateInfo struct](https://pkg.go.dev/github.com/sylabs/sif/pkg/sif#CreateInfo) should ensure the `ID` field is generated using a version of `github.com/satori/go.uuid` that is not vulnerable to this issue. Unfortunately, the latest tagged release is vulnerable to this issue. One way to obtain a non-vulnerable version is: ``` go get github.com/satori/go.uuid@75cca531ea763666bc46e531da3b4c3b95f64557 ``` ### References * https://github.com/satori/go.uuid/issues/73 ### For more information If you have any questions or comments about this advisory: * Open an issue in [github.com/sylabs/sif](https://github.com/sylabs/sif/issues/new) * Email us at [security@sylabs.io](mailto:security@sylabs.io)

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
