RHEL 7 : freeradius (RHSA-2017:2389)

critical Nessus Plugin ID 102119

Language:

Synopsis

The remote Red Hat host is missing one or more security updates for freeradius.

Description

The remote Redhat Enterprise Linux 7 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2017:2389 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 out-of-bounds write flaw was found in the way FreeRADIUS server handled certain attributes in request packets. A remote attacker could use this flaw to crash the FreeRADIUS server or to execute arbitrary code in the context of the FreeRADIUS server process by sending a specially crafted request packet.
(CVE-2017-10984)

* An out-of-bounds read and write flaw was found in the way FreeRADIUS server handled RADIUS packets. A remote attacker could use this flaw to crash the FreeRADIUS server by sending a specially crafted RADIUS packet. (CVE-2017-10978)

* An out-of-bounds read flaw was found in the way FreeRADIUS server handled decoding of DHCP packets. A remote attacker could use this flaw to crash the FreeRADIUS server by sending a specially crafted DHCP request. (CVE-2017-10983)

* A denial of service flaw was found in the way FreeRADIUS server handled certain attributes in request packets. A remote attacker could use this flaw to cause the FreeRADIUS server to enter an infinite loop, consume increasing amounts of memory resources, and ultimately crash by sending a specially crafted request packet. (CVE-2017-10985)

* Multiple out-of-bounds read flaws were found in the way FreeRADIUS server handled decoding of DHCP packets. A remote attacker could use these flaws to crash the FreeRADIUS server by sending a specially crafted DHCP request. (CVE-2017-10986, CVE-2017-10987)

Red Hat would like to thank the FreeRADIUS project for reporting these issues. Upstream acknowledges Guido Vranken as the original reporter of these issues.

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

Note that Nessus has not tested for these issues 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-2017:2389.
