April 23, 2015

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

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

- Ubuntu 14.10
- Ubuntu 14.04 LTS

Summary:

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

Software Description:
- wpa: client support for WPA and WPA2

Details:

It was discovered that wpa_supplicant incorrectly handled SSID information
when creating or updating P2P peer entries. A remote attacker could use
this issue to cause wpa_supplicant to crash, resulting in a denial of
service, expose memory contents, or possibly execute arbitrary code.

Update instructions:

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

Ubuntu 14.10:
  wpasupplicant                   2.1-0ubuntu4.1

Ubuntu 14.04 LTS:
  wpasupplicant                   2.1-0ubuntu1.2

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