USN-2383-1: wpa_supplicant vulnerability

14 October 2014

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



  • 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.

Update instructions

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

Ubuntu 14.04
Ubuntu 12.04
Ubuntu 10.04

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