+ <background>
+ <p>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.
+ </p>
+ </background>
+ <description>
+ <p>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.
+ </p>
+ </description>
+ <impact type="normal">
+ <p>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.
+ </p>
+ </impact>
+ <workaround>
+ <p>There is no known workaround at this time.</p>
+ </workaround>
+ <resolution>
+ <p>All hostapd users should upgrade to the latest version:</p>
+
+ <code>
+ # emerge --sync
+ # emerge --ask --oneshot --verbose "&gt;=net-wireless/hostapd-2.6-r1"
+ </code>
+
+ <p>All wpa_supplicant users should upgrade to the latest version:</p>
+
+ <code>
+ # emerge --sync
+ # emerge --ask --oneshot --verbose
+ "&gt;=net-wireless/wpa_supplicant-2.6-r3"
