USN-2577-1: wpa_supplicant vulnerability

23 April 2015

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



  • wpa - client support for WPA and WPA2


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 15.04
Ubuntu 14.10
Ubuntu 14.04

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