3. Description:
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.
