CVE-2022-37966 s4:kdc: announce PA-SUPPORTED-ETYPES like windows.
We need to take the value from the msDS-SupportedEncryptionTypes
attribute and only take the default if there's no value or
if the value is 0.
For krbtgt and DC accounts we need to force support for
ARCFOUR-HMAC-MD5 and AES encryption types and add the related bits
in addtition. (Note for krbtgt msDS-SupportedEncryptionTypes is
completely ignored the hardcoded value is the default, so there's
no AES256-SK for krbtgt).
For UF_USE_DES_KEY_ONLY on the account we reset
the value to 0, these accounts are in fact disabled completely,
as they always result in KRB5KDC_ERR_ETYPE_NOSUPP.
Then we try to get all encryption keys marked in
supported_enctypes, and the available_enctypes
is a reduced set depending on what keys are
actually stored in the database.
We select the supported session key enctypes by the available
keys and in addition based on AES256-SK as well as the
"kdc force enable rc4 weak session keys" option.

CVE-2022-38023 docs-xml/smbdotconf: change 'reject md5 clients' default to yes
AES is supported by Windows Server >= 2008R2, Windows (Client) >= 7 and Samba >= 4.0,
so there's no reason to allow md5 clients by default.
However some third party domain members may need it.

CVE-2022-44640 HEIMDAL: asn1: invalid free in ASN.1 codec
Heimdal's ASN.1 compiler generates code that allows specially
crafted DER encodings of CHOICEs to invoke the wrong free function
on the decoded structure upon decode error. This is known to impact
the Heimdal KDC, leading to an invalid free() of an address partly
or wholly under the control of the attacker, in turn leading to a
potential remote code execution (RCE) vulnerability.
This error affects the DER codec for all CHOICE types used in
Heimdal, though not all cases will be exploitable. We have not
completed a thorough analysis of all the Heimdal components
affected, thus the Kerberos client, the X.509 library, and other
parts, may be affected as well.
This bug has been in Heimdal since 2005. It was first reported by
Douglas Bagnall, though it had been found independently by the
Heimdal maintainers via fuzzing a few weeks earlier.
