In versions prior to 2.8.1the `github.com/sylabs/sif/v2/pkg/integrity` package did not verify that the hash algorithm(s) used are cryptographically secure when verifying digital signatures. A patch is available in version >= v2.8.1 of the module. Users are encouraged to upgrade. Users unable to upgrade may independently validate that the hash algorithm(s) used for metadata digest(s) and signature hash are cryptographically secure.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","score":9.8},"cwes":["CWE-327","CWE-347"],"references":["https://github.com/sylabs/sif/commit/07fb86029a12e3210f6131e065570124605daeaa","https://github.com/sylabs/sif/security/advisories/GHSA-m5m3-46gj-wch8","https://security.gentoo.org/glsa/202210-19","https://github.com/sylabs/sif/commit/07fb86029a12e3210f6131e065570124605daeaa","https://github.com/sylabs/sif/security/advisories/GHSA-m5m3-46gj-wch8"],"products":["sylabs:singularity_image_format"],"source":"nvd","synced_at":"2026-10-19T21:36:05.460296998+00:00"},"epss":{"cve":"CVE-2022-39237","score":0.0065,"percentile":0.51174,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-m5m3-46gj-wch8","url":"https://osv.dev/vulnerability/GHSA-m5m3-46gj-wch8","summary":"SIF's Digital Signature Hash Algorithms Not Validated","modified":"2023-11-08T04:10:16.141610Z","packages":[{"ecosystem":"Go","name":"github.com/sylabs/sif/v2","purl":"pkg:golang/github.com/sylabs/sif/v2","ranges":["<2.8.1"],"fixed":["2.8.1"]}]},{"id":"GO-2022-1045","url":"https://osv.dev/vulnerability/GO-2022-1045","summary":"Improper validation of signature hash algorithms in github.com/sylabs/sif/v2","modified":"2024-05-20T16:03:47Z","packages":[{"ecosystem":"Go","name":"github.com/sylabs/sif/v2","purl":"pkg:golang/github.com/sylabs/sif/v2","ranges":["<2.8.1"],"fixed":["2.8.1"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
