Synopsis
Moderate: authconfig security, bug fix, and enhancement update
Type/Severity
Security Advisory: Moderate
Topic
An update for authconfig is now available for Red Hat Enterprise Linux 7.
Red Hat Product Security has rated this update as having a security impact of Moderate. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section.
Description
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.
