wpa vulnerability
==========================================================================

A security issue affects these releases of Ubuntu and its derivatives:

– Ubuntu 14.04 ESM

Summary:

wpa_supplicant could be made to crash or run programs if it received
specially crafted network traffic.

Software Description:

Details:

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.

Update instructions:

The problem can be corrected by updating your system to the following
package versions:

Ubuntu 14.04 ESM:
wpasupplicant 2.1-0ubuntu1.7+esm4

After a standard system update you need to reboot your computer to make
all the necessary changes.
