Users are encouraged to upgrade.\n\nThe patch is commit https://github.com/sylabs/sif/commit/193962882122abf85ff5f5bcc86404933e71c07d\n\n### Workarounds\nUsers 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:\n\n```\ngo get github.com/satori/go.uuid@75cca531ea763666bc46e531da3b4c3b95f64557\n```\n\n### References\n*
