EulerOS 2.0 SP2 : freeradius (EulerOS-SA-2017-1168)

High Nessus Plugin ID 103006

Synopsis

The remote EulerOS host is missing multiple security updates.

Description

According to the versions of the freeradius package installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :

- An integer overflow leading to a heap-buffer overflow was found in the libnl library. An attacker could use this flaw to cause an application compiled with libnl to crash or possibly execute arbitrary code in the context of the user running such an application.
(CVE-2017-0553)

- 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)

- 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)

- 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)

- 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)

- 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)

Note that Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
