Fedora 30 Security Advisory: Hostapd Cache Attacks and EAP-Pwd Issues

hostapd is a user space daemon for access point and authentication servers. It

implements IEEE 802.11 access point management, IEEE 802.1X/WPA/WPA2/EAP

Authenticators and RADIUS authentication server.

hostapd is designed to be a "daemon" program that runs in the back-ground and

acts as the backend component controlling authentication. hostapd supports

separate frontend programs and an example text-based frontend, hostapd_cli, is

included with hostapd.
