[SECURITY] Fedora 30 Update: hostapd-2.7-2.fc30

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 a nd acts as the backe...

DEBIAN-CVE-2019-11555

The EAP-pwd implementation in hostapd EAP server before 2.8 and wpasupplicant EAP peer before 2.8 does not validate fragmentation reassembly state properly for a case where an unexpected fragment could be received. This could result in process termination due to a NULL pointer dereference denial ...
