USN-5825-2: PAM regressions
6 February 2023
USN-5825-1 caused some minor regressions in PAM.
- pam - Pluggable Authentication Modules
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.

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.
The problem can be corrected by updating your system to the following package versions:
In general, a standard system update will make all the necessary changes.
- USN-5825-1: libpam0g, libpam-modules-bin, libpam-modules, pam, libpam-runtime, libpam-doc, libpam0g-dev, libpam-cracklib
