RHEL 7 : freeradius (RHSA-2017:1581)

critical Nessus Plugin ID 101078

Synopsis

The remote Red Hat host is missing a security update for freeradius.

Description

The remote Redhat Enterprise Linux 7 host has packages installed that are affected by a vulnerability as referenced in the RHSA-2017:1581 advisory.

FreeRADIUS is a high-performance and highly configurable free Remote Authentication Dial In User Service (RADIUS) server, designed to allow centralized authentication and authorization for a network.

Security Fix(es):

* An authentication bypass flaw was found in the way the EAP module in FreeRADIUS handled TLS session resumption. A remote unauthenticated attacker could potentially use this flaw to bypass the inner authentication check in FreeRADIUS by resuming an older unauthenticated TLS session. (CVE-2017-9148)

Tenable has extracted the preceding description block directly from the Red Hat Enterprise Linux security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Update the RHEL freeradius package based on the guidance in RHSA-2017:1581.
