Summary
pam regressions
Details

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.
