1 User-Visible krb5-strength Changes
3 krb5-strength 2.0 (unreleased)
5 Add support for the MIT Kerberos password quality plugin interface,
6 available in MIT Kerberos 1.9 and later, contributed by Greg Hudson
7 and MIT. Drop the patch for MIT Kerberos 1.4 (and hence support for
8 versions of MIT Kerberos prior to 1.9).
10 Add support for building with TinyCDB and then checking passwords
11 against a CDB database. There is a new password_dictionary_cdb
12 krb5.conf configuration setting that configures a CDB directory to
13 use. The tests with a CDB dictionary are much simpler: passwords are
14 rejected if found in the dictionary either literally, with one or two
15 characters removed from the start or end, or with one character
16 removed from both the start and the end. Both a CrackLib and a CDB
17 dictionary can be specified to check both dictionaries. A new
18 cdbmake-wordlist utility (written in Perl) is included to ease the
19 process of creating a CDB database from a simple word list.
21 The plugin now sets the Kerberos error message in the context to pass
22 error information, resulting in higher-quality error reporting in the
25 CrackLib checks for passwords where a character is a simple increment
26 or decrement of the previous character. In previous versions, the
27 embedded version of CrackLib allowed at most four such occurrences in
28 the entire password. This results in false positives on long
29 passphrases, since such accidental letter relationships aren't
30 uncommon in human languages. Change the embedded CrackLib to allow
31 one such simple increment for every three characters in the password,
32 which tightens the check somewhat for shorter passwords and loosens it
33 considerably for longer passwords.
35 Expect the Heimdal password strength checking plugin header in
36 kadm5/kadm5-pwcheck.h instead of outside of the kadm5 directory. This
37 is the path used by current versions of Heimdal.
39 Update to rra-c-util 4.9:
41 * Probe for Kerberos headers using file checks instead of compiles.
42 * Improve probe for the Heimdal libroken library.
43 * Always build with large file support.
44 * Conditionally call AM_PROG_AR for portability to new Autotools.
46 Update to C TAP Harness 2.2:
48 * Allow more easily running single programs under tests/runtests.
49 * Flush the output from the test harness after each test.
51 krb5-strength 1.1 (2012-05-11)
53 Change the minimum password length in the embedded CrackLib to 8.
55 Reject passwords formed from the username portion of the principal
58 In the embedded CrackLib, also check for a duplicated dictionary word.
60 Support linking with the system CrackLib instead of the embedded and
61 stricter copy by passing --with-cracklib to configure.
63 Fix variable sizes in the embedded CrackLib on 64-bit platforms. This
64 may fix interoperability problems with databases created on platforms
65 with a different native integer size. Thanks, Karl Lehnberger and
68 Stop using local in the test suite for portability to Solaris /bin/sh.
70 Update to rra-c-util 4.4:
72 * Use PATH_KRB5_CONFIG to override krb5-config location.
73 * Fix probing for ibm_svc/krb5_svc.h on AIX.
74 * Support Heimdal libraries without libroken, like OpenBSD.
75 * Fix manual Kerberos library probing without transitive dependencies.
76 * Support systems that only have krb5/krb5.h.
77 * Pass --deps to krb5-config in the non-reduced-dependencies case.
78 * Silence __attribute__ warnings on more compilers.
79 * Update warning flags for make warnings.
80 * Flesh out MAINTCLEANFILES to remove autogen results.
81 * Add notices to all files copied from rra-c-util.
83 Update to C TAP Harness 1.12:
85 * Drop is_double from the C TAP library to avoid requiring -lm.
86 * Avoid using local in the shell libtap.sh library.
87 * Silence __attribute__ warnings on more compilers.
88 * runtests now frees all allocated resources on exit.
89 * Fix runtests to still honor SOURCE and -s without BUILD and -b.
90 * Add tests/HOWTO documenting how to add new tests.
91 * Ensure correct output ordering in test results.
92 * Add -h and a better usage message to tests/runtests.
94 krb5-strength 1.0 (2010-02-16)
96 Add heimdal-strength, a program that checks password strength using
97 the protocol for a Heimdal external check program.
99 The shared module now also exports the interface expected by Heimdal's
100 dynamically loaded password strength checking API and can be used as a
101 Heimdal kadmin plugin.
103 Add a new plugin API for MIT Kerberos modelled after the plugin API
104 used for other MIT Kerberos plugins. Thanks to Marcus Watts for
105 substantial research and contributions to the interface design. This
106 work is incomplete in this release, missing the corresponding patch to
109 Fixed the data format written by the included packer program to add
110 enough nul bytes at the end of the data. Previously, there was not
111 enough trailing nul bytes for the expected input format, leading to
112 uninitialized memory reads in the password lookup.
114 Add a test suite using the driver and library from C TAP Harness 1.1.
116 Add portability code for platforms without a working snprintf or other
117 deficiencies and updated the code to take advantage of those
120 krb5-strength 0.5 (2007-07-18)
122 The check of the password against the principal checked against the
123 fully-qualified principal, which is not the usual problem.
124 Additionally check that the password doesn't match the principal with
125 the realm removed or the reverse of that (case-insensitive).
127 krb5-strength 0.4 (2007-03-28)
129 The patches directory was omitted from the distribution. Really
132 krb5-strength 0.3 (2007-03-23)
134 Initial public release. Includes a patch for MIT Kerberos, a slightly
135 modified version of CrackLib, and glue wrapped around CrackLib to make
