From Eliter Awesomeness · May 08, 2019
Hey guys,
==========================================================================

wpa vulnerability
==========================================================================
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 19.04
- Ubuntu 18.10
- Ubuntu 18.04 LTS
- Ubuntu 16.04 LTS
Summary:
wpa_supplicant and hostapd could be made to crash if they received
specially crafted network traffic.
Software Description:
- wpa: client support for WPA and WPA2
Details:
It was discovered that wpa_supplicant and hostapd incorrectly handled
unexpected fragments when using EAP-pwd. A remote attacker could possibly
use this issue to cause a denial of service.

There is a recent security vulnerability related to WPA, which is a wireless security technology. If any of you use Ubuntu and connect that to a wireless network, I would highly recommend updated and upgrade your system to patch the security vulnerability. This vulnerability can potentially cause a Denial of Service (DOS) attack if exploited.
You can do this by opening up terminal and typing in these two commands:
sudo apt-get update
sudo apt-get -y upgrade
