========================================================================== Ubuntu Security Notice USN-2383-1 October 14, 2014
A security issue affects these releases of Ubuntu and its derivatives:
wpa_supplicant could be made to run programs if it received specially crafted network traffic.
Software Description: - wpa: client support for WPA and WPA2 - wpasupplicant: client support for WPA and WPA2
Jouni Malinen discovered that the wpa_cli tool incorrectly sanitized strings when being used with action scripts. A remote attacker could possibly use this issue to execute arbitrary commands.
The problem can be corrected by updating your system to the following package versions:
Ubuntu 14.04 LTS: wpasupplicant 2.1-0ubuntu1.1
Ubuntu 12.04 LTS: wpasupplicant 0.7.3-6ubuntu2.3
Ubuntu 10.04 LTS: wpasupplicant 0.6.9-3ubuntu3.2
After a standard system update you need to reboot your computer to make all the necessary changes.
