| Description: | Summary:
The remote host is missing an update for the 'wpa_supplicant'
package(s) announced via the referenced advisory.
Vulnerability Insight:
The wpa_supplicant packages contain an 802.1X
Supplicant with support for WEP, WPA, WPA2 (IEEE 802.11i / RSN), and various EAP
authentication methods. They implement key negotiation with a WPA Authenticator for
client stations and controls the roaming and IEEE 802.11 authentication and
association of the WLAN driver.
Security Fix(es):
* A new exploitation technique called key reinstallation attacks (KRACK)
affecting WPA2 has been discovered. A remote attacker within Wi-Fi range
could exploit these attacks to decrypt Wi-Fi traffic or possibly inject
forged Wi-Fi packets by manipulating cryptographic handshakes used by the
WPA2 protocol. (CVE-2017-13077, CVE-2017-13078, CVE-2017-13080,
CVE-2017-13087)
