Wi-Fi WPA2 Krack Attacks already fixed in Ubuntu 16.04 LTS

This day had some shocking news in the morning. All Wi-Fi devices were unsafe! A serious weaknesses in WPA2, a protocol that secures all modern protected Wi-Fi networks was discovered by a Belgian security researcher.

In particular Linux and Android devices were vulnerable.

Bad news. But Ubuntu rolled out a patch and fixed the vulnerability already today.

So running this commands will make your device safe again:

sudo apt update
sudo apt upgrade

Before the update:

wpasupplicant/xenial,now 2.4-0ubuntu6 amd64 [installed]
 client support for WPA and WPA2 (IEEE 802.11i)

After the update of today:

wpasupplicant/xenial-security,now 2.4-0ubuntu6.2 amd64 [installed]
 client support for WPA and WPA2 (IEEE 802.11i)

Changelog for the update

So, it’s safe to say, software including open source software is not without faults, but at least open source software can be fixed fast, and patches can be rolled out to all devices the same day.

Happily running Ubuntu!

I would love to run Linux on my Phone.
