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-2017-10979 [CRITICAL] CWE-787 freeradius: Out-of-bounds write in rad_coalesce()
freeradius: Out-of-bounds write in rad_coalesce()
An FR-GV-202 issue in FreeRADIUS 2.x before 2.2.10 allows "Write overflow in rad_coalesce()" - this allows remote attackers to cause a denial of service (daemon crash) or possibly execute arbitrary code.
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-2017-10979 [CRITICAL] CVE-2017-10979 freeradius: Out-of-bounds write in rad_coalesce()
CVE-2017-10979 freeradius: Out-of-bounds write in rad_coalesce()
The rad_coalesce() function checks for WiMAX attributes which are too small, but it does not check for WiMAX attributes which are too large. As a result, the server can be convinced to read past the end of an attribute, and to write past the end of memory allocated via malloc().
The data being copied is taken from the attributes following the malformed WiMAX attribute, and is under the control of the attacker. While the packet has to be a "well formed" RADIUS packet, that requirement limits only the two octets which immediately follow the malformed WiMAX attribute. After that, there are up to 245 octets copied which are the complete control of the attacker.
The issue happens when the server receives any packet containing m
