wpa_supplicant is a WPA Supplicant with support for WPA and WPA2 (IEEE 802.11i / RSN). hostapd is a user space daemon for access point and authentication servers.
WiFi Protected Access (WPA and WPA2) and it’s associated technologies are all vulnerable to the KRACK attacks. Please review the referenced CVE identifiers for details.
An attacker can carry out the KRACK attacks on a wireless network in order to gain access to network clients. Once achieved, the attacker can potentially harvest confidential information (e.g. HTTP/HTTPS), inject malware, or perform a myriad of other attacks.
There is no known workaround at this time.
All hostapd users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=net-wireless/hostapd-2.6-r1"
All wpa_supplicant users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose
">=net-wireless/wpa_supplicant-2.6-r3"
