3. Description:
Kerberos is an authentication system which allows clients and services to
authenticate to each other with the help of a trusted third party, a
Kerberos Key Distribution Center (KDC).
A buffer overflow was found in the KADM5 administration server (kadmind)
when it was used with an LDAP back end for the KDC database. A remote,
authenticated attacker could potentially use this flaw to execute arbitrary
code on the system running kadmind. (CVE-2014-4345)
All krb5 users are advised to upgrade to these updated packages, which
contain a backported patch to correct this issue. After installing the
updated packages, the krb5kdc and kadmind daemons will be restarted
automatically.
