(CVE-2010-1322)Red Hat would like to thank the MIT Kerberos Team for reporting this issue.Upstream acknowledges Mike Roszkowski as the original reporter.All krb5 users should upgrade to these updated packages, which contain abackported patch to correct this issue. After installing the updatedpackages, the krb5kdc daemon will be restarted automatically.
