"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)"
