### Impact The `github.com/sylabs/sif/v2/pkg/integrity` package does not verify that the hash algorithm(s) used are cryptographically secure when verifying digital signatures. ### Patches A patch is available in version >= v2.8.1 of the module. Users are encouraged to upgrade. The patch is commit https://github.com/sylabs/sif/commit/07fb86029a12e3210f6131e065570124605daeaa ### Workarounds Users may independently validate that the hash algorithm(s) used for metadata digest(s) and signature hash are cryptographically secure. ### References * [CVE-2004-2761](https://nvd.nist.gov/vuln/detail/cve-2004-2761) * [CVE-2005-4900](https://nvd.nist.gov/vuln/detail/cve-2005-4900) ### For more information If you have any questions or comments about this advisory: * Open an issue in [github.com/sylabs/sif](https://github.com/sylabs/sif/issues/new) * Email us at [[email protected]](mailto:[email protected])

Open Source Vulnerabilities CVE-2022-39237

syslabs/sif is the Singularity Image Format (SIF) reference implementation. 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.
