| Doc Text: |
A flaw was found in the `net` package of Go (golang). When running on Windows, the `Dial` and `LookupPort` functions can panic if they receive an input containing a NUL (0) byte. This can be triggered by a remote attacker providing a specially crafted input, leading to a denial of service (DoS) for applications using these functions.
