How to Fix CVE-2022-39237

To remediate this vulnerability, upgrade all affected Github.com/sylabs/sif/v2 dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

github.com/sylabs/sif/v2 fixed: 2.8.1 
Upgrade github.com/sylabs/sif/v2 to 2.8.1
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

inspect dependencies for github.com/sylabs/sif/v2

How to Check if You Are Affected

To determine whether your application is affected by CVE-2022-39237, inspect your project dependencies for Github.com/sylabs/sif/v2:

inspect dependencies for github.com/sylabs/sif/v2

Analyze the terminal output to locate any version of Github.com/sylabs/sif/v2 in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 2.8.1), your application is affected.

Note: Verify declared build manifests and deployed runtime container environments.
