## Overview

When curl < 7.84.0 does FTP transfers secured by krb5, it handles message verification failures wrongly. This flaw makes it possible for a Man-In-The-Middle attack to go unnoticed and even allows it to inject data to the client.

## Affected

- `curl >= 7.16.4, < 7.84.0`
- `fedora = 35`
- `debian_linux = 10.0`
- `debian_linux = 11.0`
- `clustered_data_ontap`
- `element_software`
- `hci_management_node`
- `solidfire`
- `bootstrap_os`
- `h300s_firmware`
- `h500s_firmware`
- `h700s_firmware`
- `h410s_firmware`
- `macos < 13.0`
- `universal_forwarder >= 8.2.0, < 8.2.12`
- `universal_forwarder >= 9.0.0, < 9.0.6`
- `universal_forwarder = 9.1.0`

## Remediation

Upgrade past the affected range:

- `curl 7.84.0`
- `macos 13.0`
- `universal_forwarder 9.0.6`
