Predictable SIF UUID Identifiers in github.com/sylabs/sif
### 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
```
