USN-4757-1 fixed a vulnerability in wpa_supplicant and hostapd. This update
provides the corresponding update for Ubuntu 14.04 ESM.
Original advisory details:
It was discovered that wpa_supplicant did not properly handle P2P
(Wi-Fi Direct) provision discovery requests in some situations. A
physically proximate attacker could use this to cause a denial of service
or possibly execute arbitrary code.
