Hello rmainz,

You plan to fix this soon?

Comment 4 Nalin Dahyabhai 2015-04-09 18:05:08 UTC
Going by the package changelogs, this bug appears to have been accidentally left off of the list of fixes in https://admin.fedoraproject.org/updates/FEDORA-2015-2382/krb5-1.11.5-18.fc20 and https://admin.fedoraproject.org/updates/FEDORA-2015-2347/krb5-1.12.2-14.fc21

It's fixed in F20...
-- snip --
* Wed Dec 17 2014 Roland Mainz <rmainz at redhat.com> - 1.11.5-17
- fix for CVE-2014-5353 (#1174543) "Fix LDAP misused policy
  name crash"
-- snip ..
... and F21 ...

* Wed Dec 17 2014 Roland Mainz <rmainz at redhat.com> - 1.12.2-10
- fix for CVE-2014-5353 (#1174543) "Fix LDAP misused policy
  name crash"

... and { f22, rhel66z, rhel67, rhel71 }, too.
I have the git trees and test srpms still around and all source changes have been commited. I checked it twice.

I think the problem is that the announcement tool failed somehow... ;-/

Comment 9 Roland Mainz 2015-04-09 22:57:46 UTC
Per feedback of the security people I used the web interface and marked the current { krb5-1.13.1-2.fc22 , krb5-1.12.2-16.fc21, krb5-1.11.5-20.fc20 } as builds for this CVE - this is not perfectly correct since it was fixed in an earlier build but it should at least kick-off the automated update+distribution ... ;-)

I am sorry for the mess... ;-(
