SCA: security update for github.com/sylabs/scs-library-client (GHSA-7p8m-22h4-9pj7)

high Tenable Cloud Security Plugin ID 412167

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - github.com/sylabs/scs-library-client is the Go client for the Singularity Container Services (SCS)
 Container Library Service. When the scs-library-client is used to pull a container image, with
 authentication, the HTTP Authorization header sent by the client to the library service may be incorrectly
 leaked to an S3 backing storage provider. This occurs in a specific flow, where the library service
 redirects the client to a backing S3 storage server, to perform a multi-part concurrent download.
 Depending on site configuration, the S3 service may be provided by a third party. An attacker with access
 to the S3 service may be able to extract user credentials, allowing them to impersonate the user. The
 vulnerable multi-part concurrent download flow, with redirect to S3, is only used when communicating with
 a Singularity Enterprise 1.x installation, or third party server implementing this flow. Interaction with
 Singularity Enterprise 2.x, and Singularity Container Services (cloud.sylabs.io), does not trigger the
 vulnerable flow. We encourage all users to update. Users who interact with a Singularity Enterprise 1.x
 installation, using a 3rd party S3 storage service, are advised to revoke and recreate their
 authentication tokens within Singularity Enterprise. There is no workaround available at this time.
 (CVE-2022-23538)
