User-Visible krb5-strength Changes
-krb5-strength 2.2 (unreleased)
+krb5-strength 3.1 (unreleased)
+
+ A new configuration option, cracklib_maxlen, can be set to skip
+ CrackLib checks of passwords longer than that length. The CrackLib
+ rules were designed in a world in which most passwords were four to
+ eight characters long and tend to spuriously reject longer passwords.
+ SQLite dictionaries work better for checking longer passwords and
+ passphrases. Patch from Jorj Bauer.
+
+ Change the error messages returned for passwords that fail strength
+ checking to start with a capital letter. This appears to be more
+ consistent with the error message conventions used inside Heimdal.
+
+ Change the DB_File::Lock calling method in heimdal-history to work
+ properly with the (buggy) CPAN version of DB_File::Lock, instead of
+ relying on Debian's patched version. Thanks to Bernt Jernberg for the
+ report.
+
+ Apply the SuSE patch for a buffer overflow when using duplicate rules
+ to the embedded CrackLib. No duplicating rules are used in the rule
+ set included with this package, and this package doesn't expose the
+ general API, so this was not exploitable, but best to close the latent
+ issue. (The other recent CrackLib vulnerability, CVE-2016-6318,
+ doesn't apply since all the GECOS manipulation code was removed from
+ the embedded CrackLib in this package.)
+
+ Update to rra-c-util 6.2:
+
+ * Use calloc in preference to malloc wherever appropriate.
+ * Use reallocarray in preference to realloc wherever appropriate.
+ * Suppress warnings from Kerberos headers under make warnings.
+ * Support the embedded Kerberos in Solaris 10 in library probes.
+ * Add missing va_end in xasprintf implementation.
+ * Fix logic in Test::RRA::Automake for new Automake dist checking.
+ * Fix all return-value checks for snprintf to avoid off-by-one error.
+ * Update warning flags for make warnings to GCC 6.1.0.
+ * Fix Test::RRA::Config for new "do" semantics in Perl 5.22.2.
+ * Add a new test for obsolete eyrie.org URLs.
+ * Require Test::Strict 0.25 or newer for Perl strictness checks.
+
+ Update to C TAP Harness 4.1:
+
+ * Replace all remaining uses of sprintf.
+ * Test lists may now have comments and blank lines.
+ * runtests -v will show the complete output from a test.
+ * Fix segfault in runtests when given an empty test list.
+ * Tests use C_TAP_SOURCE and C_TAP_BUILD instead of SOURCE and BUILD.
+
+krb5-strength 3.0 (2014-03-25)
+
+ The krb5-strength plugin and heimdal-strength program now support a
+ SQLite password dictionary. This format of dictionary can detect any
+ password within edit distance one of a dictionary word, meaning that
+ the dictionary word can be formed by adding, removing, or changing a
+ single character in the password. A SQLite password dictionary can be
+ used alone or in combination with any of the other supported
+ dictionary types. SQLite dictionary support is based on work by David
+ Mazières.
+
+ cdbmake-wordlist has been renamed to krb5-strength-wordlist.
+ Generating CDB dictionaries now requires the -c option; see the
+ documentation for more information. A SQLite database of dictionary
+ words can now be created instead, using the -s option.
+
+ A password history implementation for Heimdal is now included. This
+ is a separate Perl program, heimdal-history, that stacks with the
+ external program implementation of strength checking. It is not
+ available in the form of a plugin, only as a Heimdal external password
+ quality check. (MIT Kerberos provides its own password history
+ mechanism.) This program has more extensive Perl module dependencies
+ than the other programs in this distribution.
+
+ A new configuration option, minimum_different, can be set to require
+ that passwords contain at least that many unique characters. This can
+ be used to reject long strings of identical characters or short
+ patterns, which may pass other checks but still be too easy to guess.
+
+ Update to rra-c-util 5.4:
+
+ * Fix portable/krb5.h build with a C++ compiler.
+ * Use Lancaster Consensus environment variables to control tests.
+ * Work around perltidy bug that leaves behind stray log files.
+
+ Update to C TAP Harness 3.0:
+
+ * Reopen standard input to /dev/null when running a test list.
+ * Don't leak extraneous file descriptors to tests.
