How to fix?

Upgrade Debian:unstable pam to version 1.0.1-10 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream pam package and not the pam package as distributed by Debian. See How to fix? for Debian:unstable relevant fixed versions and status.

pam-auth-update for PAM, as used in Ubuntu 8.10 and 9.4, and Debian GNU/Linux, does not properly handle an "empty selection" for system authentication modules in certain rare configurations, which causes any attempt to be successful and allows remote attackers to bypass authentication.
