CentOS Errata and Security Advisory CESA-2017:2389

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.
