- Add two patches from Fedora, fixing two crashes:
  * krb5-fix_interposer.patch
  * krb5-mechglue_inqure_attrs.patch

- Update to 1.14
- dropped krb5-kvno-230379.patch
- added krbdev.mit.edu-8301.patch fixing wrong function call
Major changes in 1.14 (2015-11-20)
==================================
Administrator experience:
* Add a new kdb5_util tabdump command to provide reporting-friendly
  tabular dump formats (tab-separated or CSV) for the KDC database.
  Unlike the normal dump format, each output table has a fixed number
  of fields.  Some tables include human-readable forms of data that
  are opaque in ordinary dump files.  This format is also suitable for
  importing into relational databases for complex queries.
* Add support to kadmin and kadmin.local for specifying a single
  command line following any global options, where the command
  arguments are split by the shell--for example, "kadmin getprinc
  principalname".  Commands issued this way do not prompt for
  confirmation or display warning messages, and exit with non-zero
  status if the operation fails.
* Accept the same principal flag names in kadmin as we do for the
  default_principal_flags kdc.conf variable, and vice versa.  Also
  accept flag specifiers in the form that kadmin prints, as well as
  hexadecimal numbers.
* Remove the triple-DES and RC4 encryption types from the default
  value of supported_enctypes, which determines the default key and
  salt types for new password-derived keys.  By default, keys will
  only created only for AES128 and AES256.  This mitigates some types

From patch attached to http://krbdev.mit.edu/rt/Ticket/Display.html?id=3349,
at http://krbdev.mit.edu/rt/Ticket/Attachment/23851/13214/kvno.diff, adjusted
as needed to apply to 1.10. FIXME: I'd like to better handle cases where we
have a new key with the right version stored later in the keytab file.
Currently, we're setting up to overlook that possibility.
Note that this only affects the path taken when krb5_rd_rep() is passed a
server principal name, as without a server principal name it already tries
all of the keys it finds in the keytab, regardless of version numbers.

- Add two patches from Fedora, fixing two crashes:
* krb5-fix_interposer.patch
* krb5-mechglue_inqure_attrs.patch

Tue Dec 8 20:40:26 UTC 2015 - michael@stroeder.com
- Update to 1.14
- dropped krb5-kvno-230379.patch
- added krbdev.mit.edu-8301.patch fixing wrong function call
Major changes in 1.14 (2015-11-20)
==================================
Administrator experience:
* Add a new kdb5_util tabdump command to provide reporting-friendly
tabular dump formats (tab-separated or CSV) for the KDC database.
Unlike the normal dump format, each output table has a fixed number
of fields. Some tables include human-readable forms of data that
are opaque in ordinary dump files. This format is also suitable for
importing into relational databases for complex queries.
* Add support to kadmin and kadmin.local for specifying a single
command line following any global options, where the command
arguments are split by the shell--for example, "kadmin getprinc
principalname". Commands issued this way do not prompt for
confirmation or display warning messages, and exit with non-zero
status if the operation fails.
* Accept the same principal flag names in kadmin as we do for the
default_principal_flags kdc.conf variable, and vice versa. Also
accept flag specifiers in the form that kadmin prints, as well as
hexadecimal numbers.
* Remove the triple-DES and RC4 encryption types from the default
value of supported_enctypes, which determines the default key and
salt types for new password-derived keys. By default, keys will
only created only for AES128 and AES256. This mitigates some types
of password guessing attacks.
* Add support for directory names in the KRB5_CONFIG and
KRB5_KDC_PROFILE environment variables.
* Add support for authentication indicators, which are ticket
annotations to indicate the strength of the initial authentication.
Add support for the "require_auth" string attribute, which can be
set on server principal entries to require an indicator when
authenticating to the server.
* Add support for key version numbers larger than 255 in keytab files,
and for version numbers up to 65535 in KDC databases.
* Transmit only one ETYPE-INFO and/or ETYPE-INFO2 entry from the KDC
during pre-authentication, corresponding to the client's most
preferred encryption type.
* Add support for server name identification (SNI) when proxying KDC
requests over HTTPS.
* Add support for the err_fmt profile parameter, which can be used to
generate custom-formatted error messages.
Code quality:
* Fix memory aliasing issues in SPNEGO and IAKERB mechanisms that
could cause server crashes. [CVE-2015-2695] [CVE-2015-2696]
[CVE-2015-2698]
* Fix build_principal memory bug that could cause a KDC
crash. [CVE-2015-2697]
Developer experience:
* Change gss_acquire_cred_with_password() to acquire credentials into
a private memory credential cache. Applications can use
gss_store_cred() to make the resulting credentials visible to other
processes.
* Change gss_acquire_cred() and SPNEGO not to acquire credentials for
IAKERB or for non-standard variants of the krb5 mechanism OID unless
explicitly requested. (SPNEGO will still accept the Microsoft
variant of the krb5 mechanism OID during negotiation.)
* Change gss_accept_sec_context() not to accept tokens for IAKERB or
for non-standard variants of the krb5 mechanism OID unless an
acceptor credential is acquired for those mechanisms.
* Change gss_acquire_cred() to immediately resolve credentials if the
time_rec parameter is not NULL, so that a correct expiration time
can be returned. Normally credential resolution is delayed until
the target name is known.
* Add krb5_prepend_error_message() and krb5_wrap_error_message() APIs,
which can be used by plugin modules or applications to add prefixes
to existing detailed error messages.
* Add krb5_c_prfplus() and krb5_c_derive_prfplus() APIs, which
implement the RFC 6113 PRF+ operation and key derivation using PRF+.
* Add support for pre-authentication mechanisms which use multiple
round trips, using the the KDC_ERR_MORE_PREAUTH_DATA_REQUIRED error
code. Add get_cookie() and set_cookie() callbacks to the kdcpreauth
interface; these callbacks can be used to save marshalled state
information in an encrypted cookie for the next request.
* Add a client_key() callback to the kdcpreauth interface to retrieve
the chosen client key, corresponding to the ETYPE-INFO2 entry sent
by the KDC.
* Add an add_auth_indicator() callback to the kdcpreauth interface,
allowing pre-authentication modules to assert authentication
indicators.
* Add support for the GSS_KRB5_CRED_NO_CI_FLAGS_X cred option to
suppress sending the confidentiality and integrity flags in GSS
initiator tokens unless they are requested by the caller. These
flags control the negotiated SASL security layer for the Microsoft
GSS-SPNEGO SASL mechanism.
* Make the FILE credential cache implementation less prone to
corruption issues in multi-threaded programs, especially on
platforms with support for open file description locks.
Performance:
* On slave KDCs, poll the master KDC immediately after processing a
full resync, and do not require two full resyncs after the master
KDC's log file is reset.
User experience:
* Make gss_accept_sec_context() accept tickets near their expiration
but within clock skew tolerances, rather than rejecting them
immediately after the server's view of the ticket expiration time.

- Add two patches from Fedora, fixing two crashes:
* krb5-fix_interposer.patch
* krb5-mechglue_inqure_attrs.patch
-------------------------------------------------------------------
Tue Dec 8 20:40:26 UTC 2015 - michael@stroeder.com
- Update to 1.14
- dropped krb5-kvno-230379.patch
- added krbdev.mit.edu-8301.patch fixing wrong function call
Major changes in 1.14 (2015-11-20)
==================================
Administrator experience:
* Add a new kdb5_util tabdump command to provide reporting-friendly
tabular dump formats (tab-separated or CSV) for the KDC database.
Unlike the normal dump format, each output table has a fixed number
of fields. Some tables include human-readable forms of data that
are opaque in ordinary dump files. This format is also suitable for
importing into relational databases for complex queries.
* Add support to kadmin and kadmin.local for specifying a single
command line following any global options, where the command
arguments are split by the shell--for example, "kadmin getprinc
principalname". Commands issued this way do not prompt for
confirmation or display warning messages, and exit with non-zero
status if the operation fails.
* Accept the same principal flag names in kadmin as we do for the
default_principal_flags kdc.conf variable, and vice versa. Also
accept flag specifiers in the form that kadmin prints, as well as
hexadecimal numbers.
* Remove the triple-DES and RC4 encryption types from the default
value of supported_enctypes, which determines the default key and
salt types for new password-derived keys. By default, keys will
only created only for AES128 and AES256. This mitigates some types
of password guessing attacks.
* Add support for directory names in the KRB5_CONFIG and
KRB5_KDC_PROFILE environment variables.
* Add support for authentication indicators, which are ticket
annotations to indicate the strength of the initial authentication.
Add support for the "require_auth" string attribute, which can be
set on server principal entries to require an indicator when
authenticating to the server.
* Add support for key version numbers larger than 255 in keytab files,
and for version numbers up to 65535 in KDC databases.
* Transmit only one ETYPE-INFO and/or ETYPE-INFO2 entry from the KDC
during pre-authentication, corresponding to the client's most
preferred encryption type.
* Add support for server name identification (SNI) when proxying KDC
requests over HTTPS.
* Add support for the err_fmt profile parameter, which can be used to
generate custom-formatted error messages.
Code quality:
* Fix memory aliasing issues in SPNEGO and IAKERB mechanisms that
could cause server crashes. [CVE-2015-2695] [CVE-2015-2696]
[CVE-2015-2698]
* Fix build_principal memory bug that could cause a KDC
crash. [CVE-2015-2697]
Developer experience:
* Change gss_acquire_cred_with_password() to acquire credentials into
a private memory credential cache. Applications can use
gss_store_cred() to make the resulting credentials visible to other
processes.
* Change gss_acquire_cred() and SPNEGO not to acquire credentials for
IAKERB or for non-standard variants of the krb5 mechanism OID unless
explicitly requested. (SPNEGO will still accept the Microsoft
variant of the krb5 mechanism OID during negotiation.)
* Change gss_accept_sec_context() not to accept tokens for IAKERB or
for non-standard variants of the krb5 mechanism OID unless an
acceptor credential is acquired for those mechanisms.
* Change gss_acquire_cred() to immediately resolve credentials if the
time_rec parameter is not NULL, so that a correct expiration time
can be returned. Normally credential resolution is delayed until
the target name is known.
* Add krb5_prepend_error_message() and krb5_wrap_error_message() APIs,
which can be used by plugin modules or applications to add prefixes
to existing detailed error messages.
* Add krb5_c_prfplus() and krb5_c_derive_prfplus() APIs, which
implement the RFC 6113 PRF+ operation and key derivation using PRF+.
* Add support for pre-authentication mechanisms which use multiple
round trips, using the the KDC_ERR_MORE_PREAUTH_DATA_REQUIRED error
code. Add get_cookie() and set_cookie() callbacks to the kdcpreauth
interface; these callbacks can be used to save marshalled state
information in an encrypted cookie for the next request.
* Add a client_key() callback to the kdcpreauth interface to retrieve
the chosen client key, corresponding to the ETYPE-INFO2 entry sent
by the KDC.
* Add an add_auth_indicator() callback to the kdcpreauth interface,
allowing pre-authentication modules to assert authentication
indicators.
* Add support for the GSS_KRB5_CRED_NO_CI_FLAGS_X cred option to
suppress sending the confidentiality and integrity flags in GSS
initiator tokens unless they are requested by the caller. These
flags control the negotiated SASL security layer for the Microsoft
GSS-SPNEGO SASL mechanism.
* Make the FILE credential cache implementation less prone to
corruption issues in multi-threaded programs, especially on
platforms with support for open file description locks.
Performance:
* On slave KDCs, poll the master KDC immediately after processing a
full resync, and do not require two full resyncs after the master
KDC's log file is reset.
User experience:
* Make gss_accept_sec_context() accept tickets near their expiration
but within clock skew tolerances, rather than rejecting them
immediately after the server's view of the ticket expiration time.
