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.

Affected packages
=================

    -------------------------------------------------------------------
     Package              /     Vulnerable     /            Unaffected

Description
===========

Multiple vulnerabilities exist in both hostapd and wpa_supplicant. 
Please review the CVE identifiers for more information.

Impact

the process or cause Denial of Service.

Workaround
==========

There is no known workaround at this time.

Resolution
==========

All hostapd users should upgrade to the latest version:

  # emerge --sync
  # emerge --ask --oneshot --verbose ">=net-wireless/hostapd-2.5"

All wpa_supplicant users should upgrade to the latest version:

  # emerge --sync
  # emerge --ask --oneshot -v ">=net-wireless/wpa_supplicant-2.5-r1"
