The rad_packet_recv function in radius/packet.c suffers from a memcpy buffer overflow, resulting in an overly-large recvfrom into a fixed buffer that causes a buffer overflow and overwrites arbitrary memory. If the server connects with a malicious client, crafted client requests can remotely trigger this vulnerability.
The product copies an input buffer to an output buffer without verifying that the size of the input buffer is less than the size of the output buffer, leading to a buffer overflow.
