Minder's `HandleGithubWebhook` is susceptible to a denial of service attack from an untrusted HTTP request. The vulnerability exists before the request has been validated, and as such the request is still untrusted at the point of failure. This allows an attacker with the ability to send requests to `HandleGithubWebhook` to crash the Minder controlplane and deny other users from using it. One of the first things that `HandleGithubWebhook` does is to validate the payload signature. This is done by way of the internal helper `validatePayloadSignature`: https://github.com/stacklok/minder/blob/ee66f6c0763212503c898cfefb65ce1450c7f5ac/internal/controlplane/handlers_githubwebhooks.go#L213-L218 `validatePayloadSignature` generates a reader from the incoming request by way of the internal helper `readerFromRequest`: https://github.com/stacklok/minder/blob/ee66f6c0763212503c898cfefb65ce1450c7f5ac/internal/controlplane/handlers_githubwebhooks.go#L337-L342 To create a reader from the incomin...

Virtual private networking (VPN) companies market their services as a way to prevent anyone from snooping on your Internet usage. But new research suggests this is a dangerous assumption when connecting to a VPN via an untrusted network, because attackers on the same network could force a target's traffic off of the protection provided by their VPN without triggering any alerts to the user.
