A vulnerability has been identified in FreeRADIUS, which could be exploited by remote attackers to cause a denial of service. This issue is caused by an error when processing malformed Diameter format attributes inside an EAP-TTLS tunnel, which could be exploited by attackers to cause a vulnerable server to leak a "VALUE_PAIR" data structure and exhaust all available memory resources by sending specially crafted authentication requests.
