SingularityPRO 3.7-7 is a security and bugfix release for SingularityPRO 3.7. It addresses an issue affecting the OCI distribution-spec / image-spec, by updating dependencies that SingularityPRO uses to retrieve OCI images from registries.
CVE-2021-41190 / GHSA-77vh-xpmg-72qh: OCI specifications allow ambiguous documents that contain both "manifests" and "layers" fields. Interpretation depends on the presence / value of a Content-Type header. SingularityPRO dependencies handling the retrieval of OCI images have been updated to versions that reject ambiguous documents.
Update oras-go dependency to address push failures to some registry configurations.
Implement context cancellation when a signal is received in several CLI commands.
Ensure invalid values passed to config global --set cannot lead to an empty configuration file being written.
Ability to perform concurrent multi-part downloads for library:// URIs. Disabled by default, and is configurable in singularity.conf or via environment variables.
