Summary

The remote host is missing an update for the 'authconfig' package(s) announced via the referenced advisory.

Insight

Insight

The authconfig packages contain a command-line utility and a GUI application that can configure a workstation to be a client for certain network user information, authentication schemes, and other user information and authentication-related options. Security Fix(es): * A flaw was found where authconfig could configure sssd in a way that treats existing and non-existing logins differently, leaking information on existence of a user. An attacker with physical or network access to the machine could enumerate users via a timing attack. (CVE-2017-7488) This issue was discovered by Tomas Mraz (Red Hat) and Thorsten Scherf (Red Hat). Additional Changes: For detailed information on changes in this release, see the Red Hat Enterprise Linux 7.4 Release Notes linked from the References section.
