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)
