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.","published":"2022-10-06T00:00:00Z","modified":"2026-08-12T03:51:20.392838284Z","cvss":{"score":6.3,"severity":"MEDIUM","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:L/I:L/A:L"},"epss":null,"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"Go","name":"github.com/sylabs/sif/v2","fixedVersion":"2.8.1"}],"fix":{"url":"https://github.com/sylabs/sif/commit/07fb86029a12e3210f6131e065570124605daeaa","label":"sylabs/sif@07fb860"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2022/39xxx/CVE-2022-39237.json"},{"type":"ADVISORY","url":"https://github.com/sylabs/sif/security/advisories/GHSA-m5m3-46gj-wch8"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2022-39237"},{"type":"ADVISORY","url":"https://security.gentoo.org/glsa/202210-19"},{"type":"FIX","url":"https://github.com/sylabs/sif/commit/07fb86029a12e3210f6131e065570124605daeaa"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-12T03:51:20.392838284Z"}}
