It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2023-2023-316 advisory.

    When doing NTLM authentication, the client sends replies tocryptographic challenges back to the server.
    These replieshave variable length. Winbind did not properly bounds-checkthe lan manager response length,     which despite the lanmanager version no longer being used is still part of theprotocol.

    If the system is running Samba's ntlm_auth as authentication backendfor services like Squid (or a very     unusual configuration withFreeRADIUS), the vulnarebility is remotely exploitable

    If not so configured, or to exploit this vulnerability locally, theuser must have access to the privileged     winbindd UNIX domainsocket (a subdirectory with name 'winbindd_privileged' under statedirectory, as set     in the smb.conf).

    This access is normally only given so special system services likeSquid or FreeRADIUS, that use this     feature. (CVE-2022-2127)
