Update Information:

This update incorporates the upstream fix for possible NULL-pointer dereferences which could occur if a client sent a malformed PKINIT request to a KDC (CVE-2013-1415), or if a client sent a draft9 PKINIT request to a KDC (CVE-2012-1016).
--------------------------------------------------------------------------------
ChangeLog:

* Tue Mar  5 2013 Nalin Dahyabhai <nalin at redhat.com> 1.10.3-14
- add patch to avoid dereferencing a NULL pointer in the KDC when handling a
  draft9 PKINIT request (#917841, CVE-2012-1016)
* Thu Feb 28 2013 Nalin Dahyabhai <nalin at redhat.com> 1.10.3-13

* Mon Feb 25 2013 Nalin Dahyabhai <nalin at redhat.com> 1.10.3-12
- incorporate upstream patch to fix a NULL pointer dereference when the client
  supplies an otherwise-normal-looking PKINIT request (CVE-2013-1415, #914756)
* Mon Jan  7 2013 Nalin Dahyabhai <nalin at redhat.com> 1.10.3-11
- make -server conflict with older versions of SELinux policy that didn't
  allow us to use eventfds, which libverto's backend may depend on in order
  to properly shut down a multi-worker KDC (#871524)
* Thu Dec 13 2012 Nalin Dahyabhai <nalin at redhat.com> 1.10.3-10
- libkdb_ldap: add a workaround to keep the KDC from attempting to write to an
  entry's krbLastAdminUnlock attribute on every AS request (#860759, RT#7502)
* Tue Dec 11 2012 Nalin Dahyabhai <nalin at redhat.com> 1.10.3-9
- when building with our bundled copy of libverto, package it in with -libs
  rather than with -server (#886049)
* Mon Dec 10 2012 Nalin Dahyabhai <nalin at redhat.com> 1.10.3-8
- untag a couple of other patches which don't strictly need to apply during
  %{?_rawbuild} builds (more of #874177)
* Wed Oct 17 2012 Nalin Dahyabhai <nalin at redhat.com> 1.10.3-7
- tag a couple of other patches which we still need to be applied during
  %{?_rawbuild} builds (zmraz, #874177)
* Tue Sep 25 2012 Nalin Dahyabhai <nalin at redhat.com> 1.10.3-6
