Virtuozzo 7 : freeradius / freeradius-devel / freeradius-doc / etc (VZLSA-2017-1581)

critical Nessus Plugin ID 101534

Synopsis

The remote Virtuozzo host is missing a security update.

Description

An update for freeradius is now available for Red Hat Enterprise Linux 7.

Red Hat Product Security has rated this update as having a security impact of Important. 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.

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)

Note that Tenable Network Security has attempted to extract the preceding description block directly from the corresponding Red Hat security advisory. Virtuozzo provides no description for VZLSA advisories. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Solution

Update the affected freeradius / freeradius-devel / freeradius-doc / etc package.
