This quick tutorial outlines how to upgrade openssl to the latest version on Ubuntu Server 13.04.

A massive security hole has left over two thirds of the Internet's web servers vulnerable to the "Heartbleed Bug" which was announced to the public today. Use the following tool to check if your server is vulnerable:


You can run the following Bash script to upgrade your instance of OpenSSL to the latest version which at the time of this writing is <code>1.0.1g</code>:


# Need to upgrade an Ubuntu 13.04 server to use OpenSSL 1.0.1g?
# Read and execute this script :D
# License: WTFPL, GPLv3, MIT, whatever; just patch your shit
# http://askubuntu.com/questions/444702/how-to-patch-cve-2014-0160-in-openssl

if [[ $EUID -ne 0 ]]; then
	echo "This script must be run as root" 1>&2
	exit 1
wget https://www.openssl.org/source/openssl-1.0.1g.tar.gz
wget https://www.openssl.org/source/openssl-1.0.1g.tar.gz.asc

gpg --recv-key 0xD3577507FA40E9E2

# IMPORTANT! Manually verify that this is the correct key ID:
# http://pgp.mit.edu:11371/pks/lookup?op=vindex&search=0xD3577507FA40E9E2
# https://www.openssl.org/about/

gpg --verify openssl-1.0.1g.tar.gz.asc openssl-1.0.1g.tar.gz

if [[ $? -eq 0 ]]; then
	tar xzvf openssl-1.0.1g.tar.gz
	cd openssl-1.0.1g && sudo ./config && sudo make && sudo make install
	# To link the old openssl library to a new version
	sudo ln -sf /usr/local/ssl/bin/openssl `which openssl`
	echo "DONE!"
