Kerberos Version 5, Release 1.6.4 Release Notes The MIT Kerberos Team Unpacking the Source Distribution --------------------------------- The source distribution of Kerberos 5 comes in a gzipped tarfile, krb5-1.6.4.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 krb5-1.6.4.tar.gz If you don't have GNU tar, you will need to get the FSF gzip distribution and use gzcat: gzcat krb5-1.6.4.tar.gz | tar xpf - Both of these methods will extract the sources into krb5-1.6.4/src and the documentation into krb5-1.6.4/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 email@example.com. You may view bug reports by visiting http://krbdev.mit.edu/rt/ and logging in as "guest" with password "guest". Major changes in krb5-1.6.4 ---------------------------  Fix long-standing bug in libdb btree page splits that could cause database corruption under unusual circumstances. This is believed to be one of the major causes of unexplained database corruption events reported to us over many years.  Fix MITKRB5-SA-2008-002 rpc/svc.c file descriptor array overrun. [CVE-2008-0947]  Fix MITKRB5-SA-2008-001 double-free in KDC krb4 code [CVE-2008-0062], and uninitialized data in KDC krb4 code.

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. krb5-1.6 changes by ticket ID ----------------------------- Listed below are the RT tickets of bugs fixed in krb5-1.6.
