Fedora Update Notification
FEDORA-2010-1722
2010-02-18 16:58:52
--------------------------------------------------------------------------------

Name        : krb5
Product     : Fedora 12
Version     : 1.7.1
Release     : 2.fc12
URL         : http://web.mit.edu/kerberos/www/
Summary     : The Kerberos network authentication system
Description :
Kerberos V5 is a trusted-third-party network authentication system,
which can improve your network's security by eliminating the insecure
practice of cleartext passwords.

--------------------------------------------------------------------------------
Update Information:

This update adds the upstream patch to avoid a potential denial of service
in
the KDC in versions 1.7 and later (CVE-2010-0283).  It obsoletes a previous
pending update to version 1.7.1, which incorporates a fix to avoid
accidentally
tripping account lockout logic on AD servers when the user types in the
wrong
password.
--------------------------------------------------------------------------------
ChangeLog:

* Tue Feb 16 2010 Nalin Dahyabhai  - 1.7.1-2
- apply patch from upstream to fix KDC denial of service (CVE-2010-0283,
* Wed Feb  3 2010 Nalin Dahyabhai  - 1.7.1-1
- update to 1.7.1
  - don't trip AD lockout on wrong password (#542687, #554351)
  - incorporates fixes for CVE-2009-4212 and CVE-2009-3295
  - fixes gss_krb5_copy_ccache() when SPNEGO is used
- move sim_client/sim_server, gss-client/gss-server, uuclient/uuserver to
  the devel subpackage, better lining up with the expected krb5/krb5-appl
  split in 1.8
- drop kvno,kadmin,k5srvutil,ktutil from -workstation-servers, as it
already
  depends on -workstation which also includes them
* Mon Jan 25 2010 Nalin Dahyabhai  - 1.7-23
- tighten up default permissions on kdc.conf and kadm5.acl (#558343)
* Fri Jan 22 2010 Nalin Dahyabhai  - 1.7-22
- use portreserve correctly -- portrelease takes the basename of the file
  whose entries should be released, so we need three files, not one
* Mon Jan 18 2010 Nalin Dahyabhai  - 1.7-21
- suppress warnings of impending password expiration if expiration is more
than
  seven days away when the KDC reports it via the last-req field, just as
we
  already do when it reports expiration via the key-expiration field

- link with libtinfo rather than libncurses, when we can, in future RHEL
* Fri Jan 15 2010 Nalin Dahyabhai  - 1.7-20

  when checking whether or not we get to use the prompter callback
(#555875)
* Thu Jan 14 2010 Nalin Dahyabhai  - 1.7-19
- use portreserve to make sure the KDC can always bind to the kerberos-iv
  port, kpropd can always bind to the krb5_prop port, and that kadmind can
  always bind to the kerberos-adm port (#555279)
- correct inadvertent use of macros in the changelog (rpmlint)
* Tue Jan 12 2010 Nalin Dahyabhai  - 1.7-18
- add upstream patch for integer underflow during AES and RC4 decryption
  (CVE-2009-4212), via Tom Yu (#545015)
* Wed Jan  6 2010 Nalin Dahyabhai  - 1.7-17
- put the conditional back for the -devel subpackage

  alternate version was incomplete

  only one installed (#529319)

- and put it back in

- make krb5-config suppress CFLAGS output when called with --libs (#544391)
* Thu Dec  3 2009 Nalin Dahyabhai  - 1.7-11
- ksu: move account management checks to before we drop privileges, like
  su does (#540769)
- selinux: set the user part of file creation contexts to match the current
  context instead of what we looked up
