-From: Robbie Harwood <rharwood@redhat.com>
-Date: Fri, 9 Nov 2018 15:12:21 -0500
-Subject: [PATCH] [downstream] FIPS with PRNG and RADIUS and MD4
-
-NB: Use openssl's PRNG in FIPS mode and taint within krad.
-
-A lot of the FIPS error conditions from OpenSSL are incredibly
-mysterious (at best, things return NULL unexpectedly; at worst,
-internal assertions are tripped; most of the time, you just get
-ENOMEM).  In order to cope with this, we need to have some level of
-awareness of what we can and can't safely call.
-
-This will slow down some calls slightly (FIPS_mode() takes multiple
-locks), but not for any ciphers we care about - which is to say that
-AES is fine.  Shame about SPAKE though.
-
-post6 restores MD4 (and therefore keygen-only RC4).
-
-post7 restores MD5 and adds radius_md5_fips_override.
-
-post8 silences a static analyzer warning.
-
-Last-updated: krb5-1.20

-Subject: [PATCH] [downstream] Allow krad UDP/TCP localhost connection
- with FIPS
-
-libkrad allows to establish connections only to UNIX socket in FIPS
-mode, because MD5 digest is not considered safe enough to be used for
-network communication. However, FreeRadius requires connection on TCP or
-UDP ports.
-
-This commit allows TCP or UDP connections in FIPS mode if destination is
-localhost.

-Subject: [PATCH] [downstream] Allow to set PAC ticket signature as
- optional
-
-MS-PAC states that "The ticket signature SHOULD be included in tickets
-that are not encrypted to the krbtgt account". However, the
-implementation of krb5_kdc_verify_ticket() will require the ticket
-signature to be present in case the target of the request is a service
-principal.
-
-In gradual upgrade environments, it results in S4U2Proxy requests
-against a 1.20 KDC using a service ticket generated by an older version
-KDC to fail.
-
-This commit adds a krb5_kdc_verify_ticket_ext() function with an extra
-switch parameter to tolerate the absence of ticket signature in this
-scenario. If the ticket signature is present, it has to be valid,
-regardless of this parameter.
-
-This parameter is set based on the "optional_pac_tkt_chksum" string
-attribute of the TGT KDB entry.

-Subject: [PATCH] [downstream] Make PKINIT CMS SHA-1 signature
- verification available in FIPS mode
-
-We recommend using the SHA1 crypto-module in order to allow the
-verification of SHA-1 signature for CMS messages. However, this module
-does not work in FIPS mode, because the SHA-1 algorithm is absent from
-the OpenSSL FIPS provider.
-
-This commit enables the signature verification process to fetch the
-algorithm from a non-FIPS OpenSSL provider.
-
-Support for SHA-1 CMS signature is still required, especially in order
-to interoperate with Active Directory. At least it is until elliptic
-curve cryptography is implemented for PKINIT in MIT krb5.

-Subject: [PATCH] Enable PKINIT if at least one group is available
-
-OpenSSL may no longer allow decoding of non-well-known Diffie-Hellman
-group parameters as EVP_PKEY objects in FIPS mode.  However, OpenSSL
-does not know about MODP group 2 (1024-bit), which is considered as a
-custom group.  As a consequence, the PKINIT kdcpreauth module fails to
-load in FIPS mode.
-
-Allow initialization of PKINIT plugin if at least one of the MODP
-well-known group parameters successfully decodes.

-Subject: [PATCH] Replace ssl.wrap_socket() for tests
-
-The ssl.wrap_socket() function was deprecated in Python 3.7 and is
-removed in Python 3.12.  The ssl.SSLContext.wrap_socket() method
-replaces it.
-
-Bump the required Python version for tests to 3.4 for
-ssl.create_default_context().
-
-[ghudson@mit.edu: changed minimum Python version]
-
-(cherry picked from commit 0ceab6c363e65fb21d3312a663f2b9b569ecc415)

-Subject: [PATCH] Fix two unlikely memory leaks
-
-In gss_krb5int_make_seal_token_v3(), one of the bounds checks (which
-could probably never be triggered) leaks plain.data.  Fix this leak
-and use current practices for cleanup throughout the function.
-
-In xmt_rmtcallres() (unused within the tree and likely elsewhere),
-store port_ptr into crp->port_ptr as soon as it is allocated;
-otherwise it could leak if the subsequent xdr_u_int32() operation
-fails.

-
-Addition of a "cleanup" section in kinit's show_ccache() function as
-part of commit 6c5471176f5266564fbc8a7e02f03b4b042202f8 introduced a
-double-free bug, because defname is a global variable.  After the
-first call, successive calls may take place with a dangling pointer in
-defname, which will be freed if krb5_cc_get_principal() fails.
-
-Convert "defname" to a local variable initialized at the beginning of
-show_ccache().
-
-[ghudson@mit.edu: edited commit message]

-+    intervals between requests, so setting a low timeout may result in
-+    fewer requests being attempted and/or some servers not being

-Subject: [PATCH] Fix various issues detected by static analysis
-
-In klists's show_credential(), ensure that the column counter doesn't
-decrease if printf() fails.
-
-In process_k5beta7_princ(), bounds-check the e_length field.
-
-In ndr_enc_delegation_info(), initialize b so it is always valid for
-the cleanup handler.
-
-In krb5_dbe_def_decrypt_key_data(), change the flow control so ret is
-always set by the end of the function.  Return KRB5_KDB_INVALIDKEYSIZE
-if there isn't enough data in the first key_data_contents field or if
-the serialized key length is invalid.
-
-In svcauth_gss_validate(), expand rpchdr to accomodate the header plus
-MAX_AUTH_BYTES.
-
-In svcudp_reply(), change slen to unsigned to match the return type of
-XDR_GETPOS() and eliminate an unnecessary check for slen >= 0.
-
-In krb5int_pthread_loaded()(), remove pthread_equal() from the weak
-symbol checks.  It is implemented as an inline function in some glibc
-versions, which makes the comparison "&pthread_equal == 0" always
-false.
-
-[ghudson@mit.edu: further modified krb5_dbe_def_decrypt_key_data() for
-clarity; added detail to commit message]

-Date: Thu, 22 Aug 2024 17:15:50 +0200
-Subject: [PATCH] Generate and verify message MACs in libkrad
-
-Implement some of the measures specified in
-draft-ietf-radext-deprecating-radius-03 for mitigating the BlastRADIUS
-attack (CVE-2024-3596):
-
-* Include a Message-Authenticator MAC as the first attribute when
-  generating a packet of type Access-Request, Access-Reject,
-  Access-Accept, or Access-Challenge (sections 5.2.1 and 5.2.4), if
-  the secret is non-empty.  (An empty secret indicates the use of Unix
-  domain socket transport.)
-
-* Validate the Message-Authenticator MAC in received packets, if
-  present.
-
-FreeRADIUS enforces Message-Authenticator as of versions 3.2.5 and
-3.0.27.  libkrad must generate Message-Authenticator attributes in
-order to remain compatible with these implementations.
-
-[ghudson@mit.edu: adjusted style and naming; simplified some
-functions; edited commit message]
-
-ticket: 9142 (new)
-tags: pullup
-target_version: 1.21-next
-
-(cherry picked from commit 871125fea8ce0370a972bf65f7d1de63f619b06c)

-Subject: [PATCH] Add ecdsa-with-sha512/256 to supportedCMSTypes
-
-Elliptic curve certificates are already supported for PKINIT
-pre-authentication, but their associated signature types aren't
-advertized.  Add ecdsa-with-sha512 and ecdsa-with-sha256 OIDs to the
-supportedCMSTypes list sent by the client.

-Subject: [PATCH] Get rid of pkinit_crypto_openssl.h
-
-Fold pkinit_crypto_openssl.h into the one source file where it was
-used.  Also clean up the include of <arpa/inet.h>, as htonl() is no
-longer used after commit 1c87ce6c44a9de0824580a2d72a8a202237e01f4.

-Subject: [PATCH] Use SoftHSMv2 for PKCS11 PKINIT tests
-
-Instead of softpkcs11, use SoftHSMv2 to mock the PKCS11 token for
-PKINIT tests.  Use pkcs11-tool from OpenSC to initialize the token and
-import a certificate and key.  SoftHSM does not support PIN-less
-tokens (see https://github.com/opendnssec/SoftHSMv2/issues/480) so
-remove that test for now.

-Subject: [PATCH] Simplify PKINIT cert representation
-
-In the _pkinit_identity_crypto_context structure, the my_certs field
-is a stack which only ever contains one cert and is only ever used to
-retrieve that one cert.  The cert_index field is always 0.  Replace
-these fields with a my_cert field pointing directly to the X509
-certificate.
-
-Simplify crypto_cert_select_default() by making it call
-crypto_cert_select() with index 0 after verifying the certificate
-count.
-
-(cherry picked from commit f95dfb7908456f9563cee66706216a21df8d791f)

-Subject: [PATCH] Set missing mask flags for kdb5_util operations
-
-Set KADM5_TL_DATA for the use_mkey and update_princ_encryption
-commands.  (Commit c877f13c8985d820583b0d7ac1bb4c5dc36e677e did this
-for the add_new_mkey and purge_mkeys commands.)  Set appropriate flags
-for the add_random_key command.
-
-[ghudson@mit.edu: combined two commits; pruned out proposed mask flag
-additions for values represented within key data or tl-data (like
-KADM5_MKVNO), as those flags are currently only used in the kadm5
-protocol, not to communicate with the KDB module]
-
-ticket: 9158 (new)

-Subject: [PATCH] Don't issue session keys with deprecated enctypes
-
-A paper by Tom Tervoort noted that rc4-hmac pre-hashes the input for
-its checksum and GSS operations before applying HMAC, and is therefore
-potentially vulnerable to hash collision attacks if a protocol
-contains a restricted signing oracle.
-
-In light of these potential attacks, begin the functional deprecation
-of DES3 and RC4 by disallowing their use as session key enctypes by
-default.  Add the variables allow_des3 and allow_rc4 in case
-negotiability of these enctypes for session keys needs to be turned
-back on, with the expectation that in future releases the enctypes
-will be more comprehensively deprecated.

-Subject: [PATCH] Add PKINIT paChecksum2 from MS-PKCA v20230920
-
-In 2023, Microsoft updated MS-PKCA to add the optional paChecksum2
-element in the PKAuthenticator sequence.  This checksum accepts SHA-1,
-SHA-256, SHA-384, and SHA-512 digests.
-
-In Windows Server 2025, this checksum becomes mandatory when using
-PKINIT with FFDH (but strangely not with ECDH if SHA-1 is configured as
-allowed).

-Subject: [PATCH] [downstream] Do not block HMAC-MD4/5 in FIPS mode
-
-To ensure RC4 HMAC-MD5 was not used in FIPS mode, access to HMAC-MD4/5
-was not allowed in this mode. However, since we provide the
-"radius_md5_fips_override" configuration parameter to allow using RADIUS
-regardless to the FIPS restrictions, we should allow HMAC-MD5 to be used
-too in this case, because it is required for the newly supported
-Message-Authenticator attribute.
-
-A FIPS mode check is added in calculate_mac() which will fail if
-"radius_md5_fips_override" is not true. It will not affect interactions
-between krb5kdc and ipa-otpd, because the Message-Authenticator
-attribute is not generated in this case.

-Subject: libkrb5: in case PKINIT is configured, attempt Anonymous
- PKINIT for FAST
-
-If auto_fast_armor is configured for the realm or globally, optimistically
-assume that Anonymous PKINIT is supported as well and try to obtain it for
-FAST use in case no pre-made FAST channel was established by the caller.
-
-This behavior will automatically enable use of passwordless pre-authentication
-methods which rely on FAST channel presence in deployments such as FreeIPA.
-
-Notably, Microsoft Active Directory KDCs do not support Anonymous PKINIT. For
-these deployments only a machine account (host keytab) can be used to build a
-FAST channel. However, libkrb5 does not have access to /etc/krb5.keytab in a
-general case.

-Subject: [PATCH] bail if prompter is not specified but required
-
-GSSAPI gss_init_sec_context() may trigger credential re-initialization
-if the cred in ccache is expired. If automatic FAST armor is in use,
-we'd request Anonymous PKINIT and use it as an armor and this will
-enable seeing pre-authentication methods which require armor presence.
-
-OTP is one of such methods and its use requires prompter to be set,
-but GSSAPI cannot specify a prompter and thus we should fail any
-pre-auth where a prompter wasn't passed.
-
-PKINIT PKCS11 and SAM-2 preauth methods use KRB5_LIBOS_CANTREADPWD while PKINIT
-and gic_pwd.c use EIO. Use EIO here because we technically attempt to read a
-PIN rather than a password.

+Subject: [PATCH] Add KDC pre-send and post-receive KDC hooks
+
+Add two new APIs, krb5_set_kdc_send_hook() and
+krb5_set_kdc_recv_hook(), which can be used to inspect and override
+messages sent to KDCs.

+Subject: [PATCH] Add OS prng intended for use with getrandom()
+
+Add the prng_os.c module, using the name previously occupied by what
+is now prng_device.c.  Unlike prng_device.c, this PRNG module
+maintains no file descriptor and just uses k5_os_random(), which is
+most efficient on platforms which have a getrandom() system call.

+decrypted, or when encrypted timestamp preauth fails against an MIT
+krb5 1.14 or earlier KDC.  Expand this check to include general

+Subject: [PATCH] Preserve GSS context on init/accept failure
+
+After gss_init_sec_context() or gss_accept_sec_context() has created a
+context, don't delete the mechglue context on failures from subsequent
+calls, even if the mechanism deletes the mech-specific context (which
+is allowed by RFC 2744 but not preferred).  Check for union contexts
+with no mechanism context in each GSS function which accepts a
+gss_ctx_id_t.
+
+CVE-2017-11462:
+
+RFC 2744 permits a GSS-API implementation to delete an existing
+security context on a second or subsequent call to
+gss_init_sec_context() or gss_accept_sec_context() if the call results
+in an error.  This API behavior has been found to be dangerous,
+leading to the possibility of memory errors in some callers.  For
+safety, GSS-API implementations should instead preserve existing
+security contexts on error until the caller deletes them.
+
+All versions of MIT krb5 prior to this change may delete acceptor
+contexts on error.  Versions 1.13.4 through 1.13.7, 1.14.1 through
+1.14.5, and 1.15 through 1.15.1 may also delete initiator contexts on
+error.

+Subject: [PATCH] Prevent KDC unset status assertion failures
+
+Assign status values if S4U2Self padata fails to decode, if an
+S4U2Proxy request uses invalid KDC options, or if an S4U2Proxy request
+uses an evidence ticket which does not match the canonicalized request
+server principal name.  Reported by Samuel Cabrero.
+
+If a status value is not assigned during KDC processing, default to
+"UNKNOWN_REASON" rather than failing an assertion.  This change will
+prevent future denial of service bugs due to similar mistakes, and
+will allow us to omit assigning status values for unlikely errors such
+as small memory allocation failures.
+
+CVE-2017-11368:
+
+In MIT krb5 1.7 and later, an authenticated attacker can cause an
+assertion failure in krb5kdc by sending an invalid S4U2Self or
+S4U2Proxy request.

+Subject: [PATCH] Use fallback realm for GSSAPI ccache selection
+
+In krb5_cc_select(), if the server principal has an empty realm, use
+krb5_get_fallback_host_realm() and set the server realm to the first
+fallback found.  This helps with the selection of a non-default ccache
+when there is no [domain_realms] configuration for the server domain.
+Modify t_ccselect.py tests to account for fallback behavior.
