Summary

Closes two dependabot alerts (both medium severity, same underlying vulnerability):

  • github.com/aws/aws-sdk-go-v2/service/lambda v1.74.0 → v1.89.1 (patched at v1.88.5)
  • github.com/aws/aws-sdk-go-v2/aws/protocol/eventstream v1.7.0 → v1.7.9 (patched at v1.7.8)

The eventstream decoder could panic on malformed input, allowing a DoS against the SDK caller.

Also regenerates aws/bootstrap.zip so the embedded Lambda binary uses the patched SDK. Without this regeneration, go install github.com/Owloops/updo@latest users would still ship the vulnerable SDK in their deployed Lambdas.

Pre-release hardening for v0.4.7.

Test plan

  • go build ./...
  • go vet ./...
  • go test ./... (no regression)
  • make build-lambda reproduces aws/bootstrap.zip
