CVE-2022-24705: Accel-Ppp

Critical severity, CVSS 9.8. EPSS: 1.2% chance of exploitation in the next 30 days.

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.

Affected products
