Serious security threat to many Internet users highlighted
Communications involving Linux and Android systems can be compromised
quickly, easily and from anywhere

Date: August 9, 2016
Source: University of California - Riverside
Summary: Researchers have identified a weakness in the Transmission
Control Protocol of all Linux operating systems since late 2012 that
enables attackers to hijack users' internet communications completely
remotely.

I read the above mentioned sciencedaily article. I am wondering whether I should follow their suggestion and make the changes to /etc/sysctl.conf or leave it alone. Has mint patched this problem?

I were you, I should make the following changes to /etc/sysctl.conf:

Code: Select all

echo 'net.ipv4.tcp_challenge_ack_limit = 999999999' | sudo tee -a /etc/sysctl.conf
sudo sysctl -p
