It implements key negotiation with a WPA Authenticator for client\nstations and controls the roaming and IEEE 802.11 authentication and\nassociation of the WLAN driver.\n\nAn integer underflow flaw, leading to a buffer over-read, was found in the\nway wpa_supplicant handled WMM Action frames. A specially crafted frame\ncould possibly allow an attacker within Wi-Fi radio range to cause\nwpa_supplicant to crash. (CVE-2015-4142)\n\nThis update includes the following enhancement:\n\n* Prior to this update, wpa_supplicant did not provide a way to require the\nhost name to be listed in an X.509 certificate's Common Name or Subject\nAlternative Name, and only allowed host name suffix or subject substring\nchecks. This update introduces a new configuration directive,\n'domain_match', which adds a full host name check. (BZ#1186806)\n\nAll wpa_supplicant users are advised to upgrade to this updated package,\nwhich contains a backported patch to correct this issue and adds this\nenhancement. After installing this update, the wpa_supplicant service will\nbe restarted automatically.",
