------------------------------------------------------------------------------- - 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@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@redhat.com> 1.10.3-13 - fix a memory leak when acquiring credentials using a keytab (RT#7586, #911110) * Mon Feb 25 2013 Nalin Dahyabhai <nalin@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@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@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@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@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@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@redhat.com> 1.10.3-6 - actually pull up the patch for RT#7063, and not some other ticket (#773496) ------------------------------------------------------------------------------- - References:
