Description

The remote host is affected by the vulnerability described in GLSA-202210-19 (Apptainer: Lack of Digital Signature Hash Verification)

 - 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.
 (CVE-2022-39237)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

All Apptainer users should upgrade to the latest version:

 # emerge --sync # emerge --ask --oneshot --verbose >=app-containers/apptainer-1.1.2
