                  Kerberos Version 5, Release 1.6.1

                            Release Notes
                        The MIT Kerberos Team

Unpacking the Source Distribution
---------------------------------

The source distribution of Kerberos 5 comes in a gzipped tarfile,
krb5-1.6.1.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 krb5-1.6.1.tar.gz

If you don't have GNU tar, you will need to get the FSF gzip
distribution and use gzcat:

        gzcat krb5-1.6.1.tar.gz | tar xpf -

Both of these methods will extract the sources into krb5-1.6.1/src and
the documentation into krb5-1.6.1/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.

Major changes in krb5-1.6
-------------------------

* Partial client implementation to handle server name referrals.

* Pre-authentication plug-in framework, donated by Red Hat.

* LDAP KDB plug-in, donated by Novell.

* Fix for MITKRB5-SA-2006-002: the RPC library could call an
  uninitialized function pointer, which created a security
  vulnerability for kadmind.

* Fix for MITKRB5-SA-2006-003: the GSS-API mechglue layer could fail
  to initialize some output pointers, causing callers to attempt to
  free uninitialized pointers.  This caused a security vulnerability
  in kadmind.

Note that the implementation of referral handling involves a change to
the behavior of krb5_sname_to_principal() to return a zero-length
realm name if it is unable to find the realm corresponding to the
hostname.  This special realm name signals the ticket-acquisition code
to request KDC canonicalization of service principal names.  Other
library code has changed to accommodate this new behavior.  This
particular method of implementing service principal name referral
handling may change in the future; we invite discussion on this
subject.

Major known bugs in krb5-1.6
----------------------------

5293    crash creating db2 database in non-existent directory

  Attempting to create a KDB in a non-existent directory using the
  Berkeley DB back end may cause a crash resulting from a null pointer
  dereference.  If a core dump occurs, this may cause a local exposure
  of sensitive information such a master key password.  This will be
  fixed in an upcoming patch release.
