Tackling the integer overflow flaw in hostapd for Fedora 21 to boost overall system safety and dependability.
Security update for integer underflow in AP mode WMM Action frame processing.

Summary

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.
