March 03, 2021
A security issue affects these releases of Ubuntu and its derivatives:
– Ubuntu 20.10
– Ubuntu 20.04 LTS
– Ubuntu 18.04 LTS
– Ubuntu 16.04 LTS
wpa_supplicant could be made to crash or run programs if it received
specially crafted network traffic.
– wpa: client support for WPA and WPA2
It was discovered that wpa_supplicant did not properly handle P2P
(Wi-Fi Direct) provision discovery requests in some situations. A
physically proximate attacker could use this to cause a denial of service
or possibly execute arbitrary code.
The problem can be corrected by updating your system to the following
Ubuntu 20.04 LTS:
Ubuntu 18.04 LTS:
Ubuntu 16.04 LTS:
After a standard system update you need to reboot your computer to make
all the necessary changes.
