    It was discovered that Kerberos incorrectly handled creating database entries for a keyless principal when     using LDAP. An authenticated remote attacker could use this issue to cause the KDC to crash, resulting in     a denial of service. (CVE-2014-5354)

    It was discovered that Kerberos incorrectly handled memory when processing XDR data. A remote attacker     could use this issue to cause kadmind to crash, resulting in a denial of service, or possibly execute     arbitrary code. (CVE-2014-9421)
