Kerberos Version 5, Release 1.3.3 Release Notes The MIT Kerberos Team Unpacking the Source Distribution --------------------------------- The source distribution of Kerberos 5 comes in a gzipped tarfile, krb5-1.3.3.tar.gz. Instructions on how to extract the entire distribution follow. If you have the GNU tar program and gzip installed, you can simply do: gtar zxpf krb5-1.3.3.tar.gz If you don't have GNU tar, you will need to get the FSF gzip distribution and use gzcat: gzcat krb5-1.3.3.tar.gz | tar xpf - Both of these methods will extract the sources into krb5-1.3.3/src and the documentation into krb5-1.3.3/doc. Building and Installing Kerberos 5 ---------------------------------- The first file you should look at is doc/install-guide.ps; it contains the notes for building and installing Kerberos 5. The info file krb5-install.info has the same information in info file format. You can view this using the GNU emacs info-mode, or by using the standalone info file viewer from the Free Software Foundation. This is also available as an HTML file, install.html. Other good files to look at are admin-guide.ps and user-guide.ps, which contain the system administrator's guide, and the user's guide, respectively. They are also available as info files kerberos-admin.info and krb5-user.info, respectively. These files are also available as HTML files. If you are attempting to build under Windows, please see the src/windows/README file. Reporting Bugs -------------- Please report any problems/bugs/comments using the krb5-send-pr program. The krb5-send-pr program will be installed in the sbin directory once you have successfully compiled and installed Kerberos V5 (or if you have installed one of our binary distributions). If you are not able to use krb5-send-pr because you haven't been able compile and install Kerberos V5 on any platform, you may send mail to krb5-bugs@mit.edu. You may view bug reports by visiting http://krbdev.mit.edu/rt/ and logging in as "guest" with password "guest".

Prior 1.3.x releases did not save the encoded KRB-SAFE message, and experienced problems when re-encoding. Found by Scooter Morris. * [1962] MS LSA tickets with short remaining lifetimes will be rejected in favor of retrieving tickets bypassing the LSA cache. * [1973] sendto_kdc.c now closes sockets with closesocket() instead of close(), avoiding a descriptor leak on Windows. * [1979] An erroneously short initial sequence number mask has been fixed. * [2028] KfW now displays a kinit dialog when GSS fails to find tickets. * [2051] Missing exports have been added to krb4_32.def on Windows. * [2058] Some problems with krb4 ticket lifetime backdating have fixed. * [2060] GSSAPI's idea of the default ccache is less sticky now. * [2068] The profile library includes prof-int.h before conditionals that rely on it. * [2084] The resolver library is no longer referenced by library code if not building with DNS SRV record support. * [2085] Updated Windows README file to reflect current compilation requirements, etc. * [2104] On Windows, only define strcasecmp and strncasecmp replacement macros if said functions are missing. * [2106] Return an error for unimplemented ccache functions, rather than calling through a null pointer. * [2118] Applied patch from Will Fiveash to use correct parameter for KDC TCP listening sockets. * [2144,2230] Memory management errors in the Windows gss.exe test client have been fixed. * [2171] krb5_locate_kpasswd() now correctly calls htons() on the kpasswd port number. Found by Arlene Berry. * [2180] The profile library now includes pthread.h when compiled with USE_PTHREADS. * [2181, 2224] A timeout has been added to gss-server, and a missing parameter to sign_server() has been added. * [2196] config.{guess,sub} have been updated from autoconf-2.59. * [2204] Windows gss.exe now has support for specifying credentials cache, as well as some minor bugfixes. * [2210] GSSAPI accept_sec_context() no longer unconditionally sets INTEG and CONF flags in contradiction to what the initiator sent. * [2212] The GSS sample application has some additional options to support testing of SSPI vs GSSAPI. * [2217] Windows gss.exe has new UI elements to support more flag settings. * [2225] In the gss sample client, some extraneous parameters have been removed from client_establish_context(). * [2228] Copyright notices updated in GSS sample apps. * [2233] On Windows compiles with KRB5_KFW_COMPILE, the lib path for krbcc32.lib is now correct. * [2195, 2236, 2241, 2245] The Solaris 9 pty-close bug, which was affecting the test suite, has been worked around by hacking scheduler priorities. See the installation notes for details. Thanks to Bill Sommerfeld for some useful hints. * [2258] An incorrect memcpy() statement in fakeka has been fixed. Reported by David Thompson. Notes, Major Changes, and Known Bugs for 1.3.1 ---------------------------------------------- * [1681] The incorrect encoding of the ETYPE-INFO2 preauthentication hint is no longer emitted, and the both the incorrect and the correct encodings of ETYPE-INFO2 are now accepted. We STRONGLY encourage deploying krb5-1.3.1 in preference to 1.3, especially on client installations, as the 1.3 release did not conform to the internet-draft for the revised Kerberos protocol in its encoding of ETYPE-INFO2. * [1683] The non-caching getaddrinfo() API on Mac OS X, which was causing significant slowdowns under some circumstances, has been worked around. Minor changes in 1.3.1 ---------------------- * [1015] gss_accept_sec_context() now passes correct arguments to TREAD_STR() when reading options beyond the forwarded credential option. Thanks to Emily Ratliff. * [1365] The GSSAPI initiator credentials are no longer cached inside the GSSAPI library. * [1651] A buffer overflow in krb_get_admhst() has been fixed. * [1655] krb5_get_permitted_enctypes() and krb5_set_real_time() are now exported for use by Samba. * [1656] gss_init_sec_context() no longer leaks credentials under some error conditions. * [1657] krb_get_lrealm() no longer returns "ATHENA.MIT.EDU" inappropriately. * [1664] The crypto library no longer has bogus dependencies on com_err. * [1665] krb5_init_context() no longer multiply registers error tables when called more than once, preventing a memory leak. * [1666] The GSS_C_NT_* symbols are now exported from gssapi32.dll on Windows. * [1667] ms2mit now imports any tickets with supported enctypes, and does not import invalid tickets. * [1677] krb5_gss_register_acceptor_identity() no longer has an off-by-one in its memory allocation. * [1679] krb5_principal2salt is now exported on all platforms. * [1684] The file credentials cache is now supported if USE_CCAPI is defined, i.e., for KfM and KfW. * [1691] Documentation for the obsolete kdc_supported_enctypes config variable has been removed. Notes, Major Changes, and Known Bugs for 1.3 -------------------------------------------- * We now install the compile_et program, so other packages can use the installed com_err library with their own error tables. (If you use our com_err code, that is; see below.) * The header files we install now assume ANSI/ISO C ('89, not '99). We have stopped testing on SunOS 4, even with gcc. Some of our code now has C89-based assumptions, like free(NULL) being well defined, that will probably frustrate any attempts to run this code under SunOS 4 or other pre-C89 systems. * Some new code, bug fixes, and cleanup for IPv6 support. Most of the code should support IPv6 transparently now. The RPC code (and therefore the admin system, which is based on it) does not yet support IPv6. The support for Kerberos 4 may work with IPv6 in very limited ways, if the address checking is turned off. The FTP client and server do not have support for the new protocol messages needed for IPv6 support (RFC 2428). * We have upgraded to autoconf 2.52 (or later), and the syntax for specifying certain configuration options have changed. For example, autoconf 2.52 configure scripts let you specify command-line options like "configure CC=/some/path/foo-cc", so we have removed some of our old options like --with-cc in favor of this approach. * The client libraries can now use TCP to connect to the KDC. This may be necessary when talking to Microsoft KDCs (domain controllers), if they issue you tickets with lots of PAC data. * If you have versions of the com_err or ss installed locally, you can use the --with-system-et and --with-system-ss configure options to use them rather than using the versions supplied here. Note that the interfaces are assumed to be similar to those we supply; in particular, some older, divergent versions of the com_err library may not work with the krb5 sources. Many configure-time variables can be used to help the compiler and linker find the installed packages; see the build documentation for details. * The AES cryptosystem has been implemented. However, support in the Kerberos GSSAPI mechanism has not been written (or even fully specified), so it's not fully enabled. See the documentation for details. Major changes listed by ticket ID --------------------------------- * [492] PRNG breakage on 64-bit platforms no longer an issue due to new PRNG implementation. * [523] Client library is now compatible with the RC4-based cryptosystem used by Windows 2000. * [709] krb4 long lifetime support has been implemented. * [880] krb5_gss_register_acceptor_identity() implemented (is called gsskrb5_register_acceptor_identity() by Heimdal). * [1087] ftpd no longer requires channel bindings, allowing easier use of ftp from behind a NAT. * [1156, 1209] It is now possible to use the system com_err to build this release. * [1174] TCP support added to client library. * [1175] TCP support added to the KDC, but is disabled by default. * [1176] autoconf-2.5x is now required by the build system. * [1184] It is now possible to use the system Berkeley/Sleepycat DB library to build this release. * [1189, 1251] The KfM krb4 library source base has been merged. * [1190] The default KDC master key type is now triple-DES.

Thanks to Ken Hornstein. * [1343] The KDC now defaults to not answering krb4 requests. * [1344] Addressless tickets are requested by default now. * [1372] There is no longer a need to create a special keytab for kadmind. The legacy administration daemons "kadmind4" and "v5passwdd" will still require a keytab, though. * [1377, 1442, 1443] The Microsoft set-password protocol has been implemented. Thanks to Paul Nelson. * [1385, 1395, 1410] The krb4 protocol vulnerabilities [MITKRB5-SA-2003-004] have been worked around. Note that this will disable krb4 cross-realm functionality, as well as krb4 triple-DES functionality. Please see doc/krb4-xrealm.txt for details of the patch. * [1393] The xdrmem integer overflows [MITKRB5-SA-2003-003] have been fixed. * [1397] The krb5_principal buffer bounds problems [MITKRB5-SA-2003-005] have been fixed.

It is not usable for GSSAPI, though. * [1491] The client-side functionality of the krb524 library has been moved into the krb5 library. * [1550] SRV record support exists for Kerberos v4. * [1551] The heuristic for locating the Kerberos v4 KDC by prepending "kerberos." to the realm name if no config file or DNS information is available has been removed. * [1568, 1067] A krb524 stub library is built on Windows. Minor changes listed by ticket ID --------------------------------- * [90] default_principal_flags documented. * [175] Docs refer to appropriate example domains/IPs now. * [299] kadmin no longer complains about missing kdc.conf parameters when it really means krb5.conf parameters. * [318] Run-time load path for tcl is set now when linking test programs. * [443] --includedir honored now. * [479] unused argument in try_krb4() in login.c deleted. * [590] The des_read_pw_string() function in libdes425 has been aligned with the original krb4 and CNS APIs. * [608] login.krb5 handles SIGHUP more sanely now and thus avoids getting the session into a weird state w.r.t. job control. * [620] krb4 encrypted rcp should work a little better now. Thanks to Greg Hudson. * [647] libtelnet/kerberos5.c no longer uses internal include files. * [673] Weird echoing of admin password in kadmin client worked around by not using buffered stdio calls to read passwords. * [677] The build system has been reworked to allow the user to set CFLAGS, LDFLAGS, CPPFLAGS, etc. reasonably. * [680] Related to [673], rewrite krb5_prompter_posix() to no longer use longjmp(), thus avoiding some bugs relating to non-restoration of terminal settings. * [697] login.krb5 no longer zeroes out the terminal window size. * [710] decomp_ticket() in libkrb4 now looks up the local realm name more correctly. Thanks to Booker Bense. * [771] .rconf files are excluded from the release now. * [772] LOG_AUTHPRIV syslog facility is now usable for logging on systems that support it. * [844] krshd now syslogs using the LOG_AUTH facility. * [850] Berekely DB build is better integrated into the krb5 library build process. * [866] lib/krb5/os/localaddr.c and kdc/network.c use a common source for local address enumeration now. * [882] gss-client now correctly deletes the context on error. * [919] kdc/network.c problems relating to SIOCGIFCONF have been fixed. * [922] An overflow in the string-to-time conversion routines has been fixed. * [933] krb524d now handles single-DES session keys other than of type des-cbc-crc. * [935] des-cbc-md4 now included in default enctypes. * [939] A minor grammatical error has been fixed in a telnet client error message. * [953] des3 no longer failing on Windows due to SHA1 implementation problems. * [964] kdb_init_hist() no longer fails if master_key_enctype is not in supported_enctypes. * [970] A minor inconsistency in ccache.tex has been fixed. * [971] option parsing bugs rendered irrelevant by removal of unused gss mechanism. * [976] make install mentioned in build documentation. * [986] Related to [677], problems with the ordering of LDFLAGS initialization rendered irrelevant by use of native autoconf idioms. * [992] Related to [677], quirks with --with-cc no longer relevant as AC_PROG_CC is used instead now. * [999] The kdc_default_options configuration variable is now honored. Thanks to Emily Ratliff. * [1006] Client library, as well as KDC, now perform reasonable sorting of ETYPE-INFO preauthentication data. * [1055] NULL pointer dereferences in code calling krb5_change_password() have been fixed. * [1063] Initial credentials acquisition failures related to client host having a large number of local network interfaces should be fixed now. * [1064] Incorrect option parsing in the gssapi library is no longer relevant due to removal of the "v2" mechanism. * [1065, 1225] krb5_get_init_creds_password() should properly warn about password expiration. * [1066] printf() argument mismatches in rpc unit tests fixed. * [1085] The krb5.conf manpage has been re-synchronized with other documentation. * [1102] gssapi_generic.h should now work with C++. * [1135] The kadm5 ACL system is better documented. * [1136] Some documentation for the setup of cross-realm authentication has been added. * [1164] krb5_auth_con_gen_addrs() now properly returns errno instead of -1 if getpeername() fails. * [1173] Address-less forwardable tickets will remain address-less when forwarded. * [1178, 1228, 1244, 1246, 1249] Test suite has been stabilized somewhat. * [1188] As part of the modernization of our usage of autoconf, AC_CONFIG_FILES is now used instead of passing a list of files to AC_OUTPUT. * [1194] configure will no longer recurse out of the top of the source tree when attempting to locate the top of the source tree. * [1192] Documentation for the krb5 afs functionality of krb524d has been written. * [1195] Example krb5.conf file modified to include all enctypes supported by the release. * [1202] The KDC no longer rejects unrecognized flags. * [1203] krb5_get_init_creds_keytab() no longer does a double-free. * [1211] The ASN.1 code no longer passes (harmless) uninitialized values around. * [1212] libkadm5 now allows for persistent exclusive database locks. * [1217] krb5_read_password() and des_read_password() are now implemented via krb5_prompter_posix(). * [1224] For SAM challenges, omitted optional strings are no longer encoded as zero-length strings. * [1226] Client-side support for SAM hardware-based preauth implemented. * [1229] The keytab search logic no longer fails prematurely if an incorrect encryption type is found. Thanks to Wyllys Ingersoll. * [1232] If the master KDC cannot be resolved, but a slave is reachable, the client library now returns the real error from the slave rather than the resolution failure from the master. Thanks to Ben Cox. * [1234] Assigned numbers for SAM preauth have been corrected. sam-pk-for-sad implementation has been aligned. * [1237] Profile-sharing optimizations from KfM have been merged. * [1240] Windows calling conventions for krb5int_c_combine_keys() have been aligned. * [1242] Build system incompatibilities with Debian's chimeric autoconf installation have been worked around. * [1256] Incorrect sizes passed to memset() in combine_keys() operations have been corrected. * [1260] Client credential lookup now gets new service tickets in preference to attempting to use expired ticketes.
