Subject: [PATCH] [downstream] FIPS with PRNG and RADIUS and MD4
NB: Use openssl's PRNG in FIPS mode and taint within krad.
@ -19,38 +19,31 @@ post6 restores MD4 (and therefore keygen-only RC4).
post7 restores MD5 and adds radius_md5_fips_override.
post8 restores MD4/MD5 for OpenSSL 3.0
post8 silences a static analyzer warning.
Use OpenSSL 3.0 library context to access MD4 and MD5 lazily from
legacy provider if RC4 encryption type is enabled, without affecting
global context.
post9 add missing includes for FIPS_mode() macro
Remove EVP_MD_CTX_FLAG_NON_FIPS_ALLOW flag since does not have any
effect anymore.
post9 load both default and legacy provider into library context

Subject: [PATCH] Set reasonable supportedCMSTypes in PKINIT
The PKINIT client uses AuthPack.supportedCMSTypes to let the KDC know
the algorithms it supports for verification of the CMS data signature.
(The MIT krb5 KDC currently ignores this list, but other
implementations use it.)
Replace 3DES with sha512WithRSAEncryption and sha256WithRSAEncryption.
[ghudson@mit.edu: simplified code and used appropriate helpers; edited
commit message]

Subject: [PATCH] Simplify plugin loading code
Remove the USE_CFBUNDLE code, which was only used by KfM. Handle
platform conditionals according to current practice. Use
k5_dir_filenames() instead of opendir() and remove the Windows
implementation of opendir().

From 75f71ace74449a6e5154314229bfa61960cd326c Mon Sep 17 00:00:00 2001

Subject: [PATCH] Update error checking for OpenSSL CMS_verify
The code for CMS data verification was initially written for OpenSSL's
PKCS7_verify() function. It now uses CMS_verify(), but error handling
is still done using PKCS7_verify() error identifiers. Update the
recognized error codes so that the KDC generates
KDC_ERR_DIGEST_IN_SIGNED_DATA_NOT_ACCEPTED errors when appropriate.
Use ERR_peek_last_error() to observe the error generated closest to
the API surface.

Subject: [PATCH] [downstream] Catch SHA-1 digest disallowed error for
PKINIT
An OpenSSL patch causes EVP_R_INVALID_DIGEST error to be raised if
CMS_verify is called to verify a SHA-1 signature. If this error is
caught, it will now return KDC_ERR_DIGEST_IN_SIGNED_DATA_NOT_ACCEPTED.

Subject: [PATCH] Add and use ts_interval() helper
ts_delta() returns a signed result, which cannot hold an interval
larger than 2^31-1 seconds. Intervals like this have been seen when
admins set password expiration dates more than 68 years in the future.
Add a second helper ts_interval() which returns a signed result, and
has the arguments reversed so that the start time is first. Use it in
warn_pw_expiry() to handle the password expiration case, in the GSS
krb5 mech where we return an unsigned context or credential lifetime
to the caller, and in the KEYRING ccache type where we compute an
unsigned keyring timeout.

In case of ksu, the owner, group, and mode are already set using %attr()
in the specfile.

Subject: [PATCH] Add PAC full checksums
A paper by Tom Tervoort noted that computing the PAC privsvr checksum
over only the server checksum is vulnerable to collision attacks
(CVE-2022-37967). In response, Microsoft has added a second KDC
checksum over the full contents of the PAC. Generate and verify full
KDC checksums in PACs for service tickets. Update the t_pac.c ticket
test case to use a ticket issued by a recent version of Active
Directory (provided by Stefan Metzmacher).
ticket: 9084 (new)

Subject: [PATCH] Fix possible double-free during KDB creation
In krb5_dbe_def_encrypt_key_data(), when we free
key_data->key_data_contents[0], reset it to null so the caller doesn't
free it as well.
Since commit a06945b4ec267e8b80e5e8c95edd89930ff12103 this bug
manifests as a double-free during KDB creation if master key
encryption fails.

Subject: [PATCH] Fix meridian type in kadmin datetime parser
The meridian suffix is typed as "Number" in kadmin YACC file for
datetime parsing, while it should be using the "Meridian" enumeration
one.
This results in invalid Meridian value on 64-bit IBM zSystems (s390x),
causing core dumped errors on most kadmin commands where meridian
suffices are used.

Subject: [PATCH] Add KCM_OP_GET_CRED_LIST for faster iteration
For large caches, one IPC operation per credential dominates the cost
of iteration. Instead transfer the whole list of credentials to the
client in one IPC operation.
Add optional support for the new opcode to the test KCM server to
allow testing of the main and fallback code paths.

adjusted code style and comments; rewrote commit message; added
kcmserver.py support and tests]

MIT krb5 uses low bits for KRB5_TC flags, while Heimdal uses high bits

Subject: [PATCH] Fix KCM retrieval support for sssd
Commit 795ebba8c039be172ab93cd41105c73ffdba0fdb added a retrieval
handler using KCM_OP_RETRIEVE, falling back on the same error codes as
the previous KCM_OP_GET_CRED_LIST support. But sssd (as of 2.4)
returns KRB5_CC_NOSUPP instead of KRB5_CC_IO if it recognizes an
opcode but does not implement it. Add a helper function to recognize
all known unsupported-opcode error codes, and use it in kcm_retrieve()
and kcm_start_seq_get().

Subject: [PATCH] Fix KDC null deref on TGS inner body null server
After the KDC decodes a FAST inner body, it does not check for a null
server. Prior to commit 39548a5b17bbda9eeb63625a201cfd19b9de1c5b this
would typically result in an error from krb5_unparse_name(), but with
the addition of get_local_tgt() it results in a null dereference. Add
a null check.
Reported by Joseph Sutton of Catalyst.
CVE-2021-37750:
In MIT krb5 releases 1.14 and later, an authenticated attacker can
cause a null dereference in the KDC by sending a FAST TGS request with
no server field.

Subject: [PATCH] Fix KDC null deref on bad encrypted challenge
The function ec_verify() in src/kdc/kdc_preauth_ec.c contains a check
to avoid further processing if the armor key is NULL. However, this
check is bypassed by a call to k5memdup0() which overwrites retval
with 0 if the allocation succeeds. If the armor key is NULL, a call
to krb5_c_fx_cf2_simple() will then dereference it, resulting in a
crash. Add a check before the k5memdup0() call to avoid overwriting
retval.
CVE-2021-36222:
In MIT krb5 releases 1.16 and later, an unauthenticated attacker can
cause a null dereference in the KDC by sending a request containing a
PA-ENCRYPTED-CHALLENGE padata element without using FAST.

Subject: [PATCH] Fix integer overflows in PAC parsing
In krb5_parse_pac(), check for buffer counts large enough to threaten
integer overflow in the header length and memory length calculations.
Avoid potential integer overflows when checking the length of each
buffer.
CVE-2022-42898:
In MIT krb5 releases 1.8 and later, an authenticated attacker may be
able to cause a KDC or kadmind process to crash by reading beyond the
bounds of allocated memory, creating a denial of service. A
privileged attacker may similarly be able to cause a Kerberos or GSS
application service to crash. On 32-bit platforms, an attacker can
also cause insufficient memory to be allocated for the result,
potentially leading to remote code execution in a KDC, kadmind, or GSS
or Kerberos application server process. An attacker with the
privileges of a cross-realm KDC may be able to extract secrets from
the KDC process's memory by having them copied into the PAC of a new
ticket.

Subject: [PATCH] Fix k5tls module for OpenSSL 3
Starting in OpenSSL 3, connection termination without a close_notify
alert causes SSL_read() to return SSL_ERROR_SSL instead of
SSL_ERROR_SYSCALL. OpenSSL 3 also provides a new option
SSL_OP_IGNORE_UNEXPECTED_EOF which allows an application to explicitly
ignore possible truncation attacks and receive SSL_ERROR_ZERO_RETURN
instead.
Remove the call to SSL_CTX_get_options() since SSL_CTX_set_options()
doesn't clear existing options.

Subject: [PATCH] Fix kadmin -k with fallback or referral realm
kadmin -k produces a client principal name with
krb5_sname_to_principal(), but it gets converted to a string and back
due to the signature of kadm5_init_with_skey(), which loses track of
the name type, so no canonicalization is performed.
In libkadm5clnt initialization, recognize the important subset of this
case--an empty realm indicates either fallback processing or the
referral realm--and restore the host-based name type so that the
client principal can be canonicalized against the keytab.

Subject: [PATCH] Fix softpkcs11 build issues with openssl 3.0
EVP_PKEY_get0_RSA() has been modified to have const return type. Remove
its usages in favor of the EVP_PKEY interface. Also remove calls to
RSA_blinding_off(), which we don't need and would require a non-const
object. Similarly, remove RSA_set_method() calls that set a pre-existing
default.
Since softpkcs11 doesn't link against krb5 and can't use zap(), allocate
buffers with OPENSSL_malloc() so can use OPENSSL_clear_free().
Move several argument validation checks to the top of their functions.
Fix some incorrect/inconsistent log messages.

From 8f70ad82a645ccb7fb1677d260baa5e4112890d4 Mon Sep 17 00:00:00 2001

Subject: [PATCH] Fix some principal realm canonicalization cases
The no_hostrealm and subst_defrealm flags in struct canonprinc were
only applied when dns_canonicalize_hostname=fallback; in the other
cases, the initial krb5_sname_to_principal() result is treated as
canonical. For no_hostrealm this limitation doesn't currently matter,
because all uses pass a principal with no realm as input. However,
subst_defrealm is used to convert the referral realm to the default
realm in krb5_get_init_creds_keytab(), krb5_cc_cache_match(), and
gss_acquire_cred() when it needs to check the desired name against a
specified ccache.
In k5_canonprinc(), if the input principal is a
krb5_sname_to_principal() result and fallback isn't in effect, apply
subst_defrealm. Document in os-proto.h that no_hostrealm doesn't
remove an existing realm and that krb5_sname_to_principal() may
already have looked one up.

Subject: [PATCH] Handle OpenSSL 3's providers
OpenSSL 3 compartmentalizes what algorithms it uses, which for us means
another hoop to jump through to use dubious cryptography. (Right now,
we need to load "legacy" in order to access MD4 and RC4.)
Use our normal initializer logic to set up providers both in the OpenSSL
provider an the PKINIT plugin. Since DT_FINI is too late, release them
using atexit() as OpenSSL does.
(cherry picked from commit bea5a703a06da1f1ab56821b77a2d3661cb0dda4)

Subject: [PATCH] Make kprop work for dump files larger than 4GB
If the dump file size does not fit in 32 bits, encode four zero bytes
(forcing an error for unmodified kpropd) followed by the size in the
next 64 bits.
Add a functional test case, but only run it when an environment
variable is set, as processing a 4GB dump file is too
resource-intensive for make check.
[ghudson@mit.edu: edited comments and commit message; eliminated use
of defined constant in some cases; added test case]

Subject: [PATCH] Set reasonable supportedCMSTypes in PKINIT
The PKINIT client uses AuthPack.supportedCMSTypes to let the KDC know
the algorithms it supports for verification of the CMS data signature.
(The MIT krb5 KDC currently ignores this list, but other
implementations use it.)
Replace 3DES with sha512WithRSAEncryption and sha256WithRSAEncryption.
[ghudson@mit.edu: simplified code and used appropriate helpers; edited

Subject: [PATCH] Support host-based GSS initiator names
When checking if we can get initial credentials in the GSS krb5 mech,
use krb5_kt_have_match() to support fallback iteration. When scanning
the ccache or getting initial credentials, rewrite cred->name->princ
to the canonical client name. When a name check is necessary (such as
when the caller specifies both a name and ccache), use a new internal
API k5_sname_compare() to support fallback iteration. Add fallback
iteration to krb5_cc_cache_match() to allow host-based names to be
canonicalized against the cache collection.
Create and store the matching principal for acceptor names in
acquire_accept_cred() so that it isn't affected by changes in
cred->name->princ during acquire_init_cred().

Subject: [PATCH] Try harder to avoid password change replay errors
Commit d7b3018d338fc9c989c3fa17505870f23c3759a8 (ticket 7905) changed
change_set_password() to prefer TCP. However, because UDP_LAST falls
back to UDP after one second, we can still get a replay error due to a
dropped packet, before the TCP layer has a chance to retry.
Instead, try k5_sendto() with NO_UDP, and only fall back to UDP after
TCP fails completely without reaching a server. In sendto_kdc.c,
implement an ONLY_UDP transport strategy to allow the UDP fallback.

Subject: [PATCH] Use KCM_OP_RETRIEVE in KCM client
In kcm_retrieve(), try KCM_OP_RETRIEVE. Fall back to iteration if the
server doesn't implement it, or if we can an answer incompatible with
KRB5_TC_SUPPORTED_KTYPES.
In kcmserver.py, implement partial decoding for creds and cred tags so
that we can do a basic principal name match.

From 21e3b9a4463f1d1aeb71de8a27c298f1307d186b Mon Sep 17 00:00:00 2001
From: Robbie Harwood <rharwood@redhat.com>
Date: Fri, 4 Oct 2019 14:49:29 -0400
Subject: [PATCH] Use OpenSSL's KBKDF and KRB5KDF for deriving long-term keys
If supported, use OpenSSL-provided KBKDF (aes-sha2 and camellia) and
KRB5KDF (3des and aes-sha1). We already use OpenSSL's PBKDF2 where
appropriate. OpenSSL added support for these KDFs in 3.0.
OpenSSL's restrictions to use KRB5KDF in FIPS mode are bypassed in case
AES SHA-1 HMAC encryption types are allowed by the crypto policy.
(cherry picked from commit ef8d11f6fb1232201c9efd2ae2ed567023fb85d2)
[rharwood@redhat.com: 3des removal]

Subject: [PATCH] Use OpenSSL's SSKDF in PKINIT when available
Starting in 3.0, OpenSSL implements SSKDF, which is the basis of our
id-pkinit-kdf (RFC 8636). Factor out common setup code around
other_info. Adjust code to comply to existing style.
(cherry picked from commit 4376a22e41fb639be31daf81275a332d3f930996)

Subject: [PATCH] Use SHA-256 instead of SHA-1 for PKINIT CMS digest
Various organizations including NIST have been strongly recommending to
stop using SHA-1 for digital signatures for some years already. CMS
digest is used to generate such signatures, hence it should be upgraded
to use SHA-256.

Subject: [PATCH] Use newly enforced dejagnu path naming convention
Since version 1.6.3, dejagnu started to enforce a naming convention that
was already in place, but not mandatory: dejagnu test directories have
to be named "testsuite". If they don't implicit relative sub-paths
resolution (e.g. "lib", "config") is not forking.
This commit renames kadm5 library's unit tests and global tests
directories to match this requirement.
Resolves: rhbz#2053133

Subject: [PATCH 2/2] Support larger RADIUS attributes in libkrad
In kr_attrset_decode(), explicitly treat the length byte as unsigned.
Otherwise attributes longer than 125 characters will be rejected with
EBADMSG.
Add a 253-character-long NAS-Identifier attribute to the tests to make
sure that attributes with the maximal number of characters are working
as expected.
[ghudson@mit.edu: used uint8_t cast per current practices; edited
commit message]

Subject: [PATCH 1/2] Avoid use after free during libkrad cleanup
libkrad client requests contain a list of references to remotes, with
no back-references or reference counts. To prevent accesses to
dangling references during cleanup, cancel all requests on all remotes
before freeing any remotes.
Remove the code for aging out unused servers. This code was fairly
safe as all requests referencing a remote should have completed or
timed out during an hour of disuse, but in the current design we have
no way to guarantee or check that. The set of addresses we send
RADIUS requests to will generally be small, so aging out servers is
unnecessary.
