Synopsis :

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

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 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.
