cmd/go: go tool pack Does Not Sanitize Output Paths

This advisory does not affect KrakenD

This is a build-time vulnerability in the Go build tool (cmd/go). KrakenD distributes pre-compiled binaries and does not invoke the Go toolchain at runtime. End users running KrakenD as a gateway are not affected.

Addressed through routine dependency maintenance in CE 2.13.5 and EE 2.13.3.

Disclosed
