CVE-2022-24705 · CRITICAL Severity

CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H

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.
