Ubuntu Security Notice USN-5825-2
Ubuntu Security Notice 5825-2 - USN-5825-1 fixed vulnerabilities in PAM. Unfortunately that update was incomplete and could introduce a regression.
This update fixes the problem. 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.
