Hi @dilyar85 and/or @cyclexuxu 👋🏻 -
Could you take a look at the CI failure for this dependency update? It's failing with the following:
2023/11/09 03:26:14 ui: Successfully obtained the source VM IP: 1.2.3.4
2023/11/09 03:26:14 ui: Getting source VM ingress IP from the VMService object
2023/11/09 03:26:14 ui: VMService object's ingress IP is empty, continue checking...
2023/11/09 03:26:14 Retryable error: VMService object's ingress IP is empty, continue checking...

It might not be a real issue since 1 / 3 passed. Passed on Windows but failed on macOS and Linux tests. I just restarted them for another try.

So I think this occurs when the retry.Config.Run for getting the ingressIP retries at least once, which causes "VMService object's ingress IP is empty, continue checking..." to logged once. The call to checkOutputLines then reads the logged lines and fails. It seems like a bit of a timing issue. I was able to reproduce once but that was it.

Yes. So in the test code, we update the VM IP and ingressIP sequentially. However, the latter is retrieved from the retry.Config
instead of using a watch mechanism. This caused the test to fail due to a timing issue. I have created PR https://github.com/hashicorp/packer-plugin-vsphere/pull/321 to address this properly.
Thanks, Sai!
Summary
Address the following CVEs for
golang.org/x/net
:CVE-2023-39325
HTTP/2 rapid reset can cause excessive work in net/http A malicious HTTP/2 client which rapidly creates requests and immediately resets them can cause excessive server resource consumption. While the total number of requests is bounded by the http2.Server.MaxConcurrentStreams setting, resetting an in-progress request allows the attacker to create a new request while the existing one is still executing. With the fix applied, HTTP/2 servers now bound the number of simultaneously executing handler goroutines to the stream concurrency limit (MaxConcurrentStreams). New requests arriving when at the limit (which can only happen after the client has reset an existing, in-flight request) will be queued until a handler exits. If the request queue grows too large, the server will terminate the connection. This issue is also fixed in golang.org/x/net/http2 for users manually configuring HTTP/2. The default stream concurrency limit is 250 streams (requests) per HTTP/2 connection. This value may be adjusted using the golang.org/x/net/http2 package; see the Server.MaxConcurrentStreams setting and the ConfigureServer function.
CVE-2023-44487
swift-nio-http2 is vulnerable to a denial-of-service vulnerability in which a malicious client can create and then reset a large number of HTTP/2 streams in a short period of time. This causes swift-nio-http2 to commit to a large amount of expensive work which it then throws away, including creating entirely new Channels to serve the traffic. This can easily overwhelm an EventLoop and prevent it from making forward progress. swift-nio-http2 1.28 contains a remediation for this issue that applies reset counter using a sliding window. This constrains the number of stream resets that may occur in a given window of time. Clients violating this limit will have their connections torn down. This allows clients to continue to cancel streams for legitimate reasons, while constraining malicious actors.
CVE-2023-3978
Text nodes not in the HTML namespace are incorrectly literally rendered, causing text which should be escaped to not be. This could lead to an XSS attack.
