ipa: DoS attack against kerberized services by abusing password policy
FreeIPA uses a default password policy that locks an account after 5 unsuccessful authentication attempts, which allows remote attackers to cause a denial of service by locking out the account in which system services run on.
It was discovered that the default IdM password policies that lock out accounts after a certain number of failed login attempts were also applied to host and service accounts. A remote unauthenticated user could use this flaw to cause a denial of service attack against kerberized services.

CVE-2016-7030 ipa: DoS attack against kerberized services by abusing password policy
A flaw was found that allows any unauthenticated party to easily run DoS attack against kerberized services in FreeIPA/IdM realm.
FreeIPA contains MIT KDC as its main component + FreeIPA is using custom database driver for the KDC. As a side-effect of implementation, FreeIPA is enforcing password policies for all principals, including services which do not use "password" but keytab with randomly-generated/strong key.
Default password policy locks an account after 5 unsuccessful authentication attempts for 10 minutes. An attacker can use this to simply lock-out any principal, including system services.
