USN-5825-1 fixed vulnerabilities in PAM. Unfortunately that update was
incomplete and could introduce a regression. This update fixes the problem.
We apologize for the inconvenience.
Original advisory details:
It was discovered that PAM did not correctly restrict login from an IP
address that is not resolvable via DNS. An attacker could possibly use this
issue to bypass authentication.
