CVE-2017-10978 FreeRADIUS vulnerabilities
Title: FreeRADIUS vulnerabilities
Summary: Several security issues were fixed in FreeRADIUS.
Guido Vranken discovered that FreeRADIUS incorrectly handled memory when
decoding packets. A remote attacker could use this issue to cause
FreeRADIUS to crash or hang, resulting in a denial of service, or possibly
execute arbitrary code.
Instructions: In general, a standard system update will make all the necessary changes.

CVE-2017-10981 [HIGH] CWE-772 freeradius: Memory leak in fr_dhcp_decode()
freeradius: Memory leak in fr_dhcp_decode()
An FR-GV-204 issue in FreeRADIUS 2.x before 2.2.10 allows "DHCP - Memory leak in fr_dhcp_decode()" and a denial of service.
A memory leak flaw was found in the way FreeRADIUS server handles decoding of DHCP packets. A remote attacker could use this flaw to cause the FreeRADIUS server to consume an increasing amount of memory resources over time, possibly leading to a crash due to memory exhaustion, by sending specially crafted DHCP packets.

CVE-2017-10981 [HIGH] CVE-2017-10981 freeradius: Memory leak in fr_dhcp_decode()
CVE-2017-10981 freeradius: Memory leak in fr_dhcp_decode()
It was discovered that if option decoding fails, the fr_dhcp_decode() function would leak memory.
The security impact is denial of service via memory exhaustion by any network device capable of sending DHCP packets to FreeRADIUS, which sends packets with malformed options.
Affected versions: 2.0.0 through 2.2.9, inclusive.
