Overview

Affected versions of this package are vulnerable to Authentication Bypass by Spoofing. The KDC accepts kpasswd requests encrypted with any key known to it. By encrypting forged kpasswd requests with its own key, a user can change other users' passwords, enabling full domain takeover.

Workarounds:

kpasswd is not a critical protocol for the AD DC in most installations, it can be disabled by setting kpasswd port = 0 in the smb.conf.
