Vulnerability in packer project

While working on packer project, I scanned the dependency manifest and found that it uses a vulnerable version of **`github.com/aws/aws-sdk-go-v2/aws/protocol/eventstream`**. The scan revealed a denial-of-service issue where malformed EventStream headers can trigger a panic in the decoder, potentially crashing the application.

Locate the dependency manifest for the Packer project and inspect the declared github.com/aws/aws-sdk-go-v2/aws/protocol/eventstream dependency. Check the linked CVE details for the affected and fixed versions, update the dependency to a non-vulnerable release, then run the project's relevant Go tests and dependency checks to confirm the vulnerable version is gone.
