✅ Remediation
For details on how to apply this update, which includes the changes described in this advisory, refer to: https://images.redhat.com/ Workaround: To verify the integrity of Go module dependencies and detect potential tampering by a malicious proxy, users can revalidate all dependencies of the current module. This process involves removing the existing `go.sum` file and then re-generating and verifying module checksums. Execute the following commands in your module's root directory: ```bash rm go.sum go mod tidy go mod verify ``` This operation will re-download and re-verify all module dependencies. Be aware that this may affect your local module cache and could require re-building projects.
