{"id":"GHSA-4gh8-x3vv-phhg","summary":"Predictable SIF UUID Identifiers in github.com/sylabs/sif","details":"### Impact\n\nThe `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.\n\n### Patches\n\nA patch is available in version \u003e= v1.2.3 of the module. 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* https://github.com/satori/go.uuid/issues/73\n\n### For more information\nIf you have any questions or comments about this advisory:\n* Open an issue in [github.com/sylabs/sif](https://github.com/sylabs/sif/issues/new)\n* Email us at [security@sylabs.io](mailto:security@sylabs.io)\n","aliases":["CVE-2021-29499","GO-2022-0912"],"modified":"2026-05-07T05:03:08.641669825Z","published":"2021-05-18T18:30:38Z","database_specific":{"nvd_published_at":"2021-05-07T21:15:00Z","cwe_ids":["CWE-330","CWE-340"],"severity":"HIGH","github_reviewed":true,"github_reviewed_at":"2021-05-07T17:01:30Z"},"references":[{"type":"WEB","url":"https://github.com/sylabs/sif/security/advisories/GHSA-4gh8-x3vv-phhg"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2021-29499"},{"type":"WEB","url":"https://github.com/satori/go.uuid/issues/73"},{"type":"WEB","url":"https://github.com/sylabs/sif/commit/193962882122abf85ff5f5bcc86404933e71c07d"},{"type":"PACKAGE","url":"https://github.com/sylabs/sif"}],"affected":[{"package":{"name":"github.com/sylabs/sif","ecosystem":"Go","purl":"pkg:golang/github.com/sylabs/sif"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"},{"fixed":"1.2.3"}]}],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2021/05/GHSA-4gh8-x3vv-phhg/GHSA-4gh8-x3vv-phhg.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:N"}]}
