Overview

** DISPUTED ** Buffer overflow in the SMB_Connect_Server function in FreeRadius 1.1.3 and earlier allows attackers to execute arbitrary code related to the server desthost field of an SMB_Handle_Type instance. NOTE: the impact of this issue has been disputed by a reliable third party and the vendor, who states that exploitation is limited "only to local administrators who have write access to the server configuration files." CVE concurs with the dispute.
