How To Patch and Protect OpenSSL Vulnerability # CVE-2015-0291 CVE-2015-0204 [ 19/March/2015 ]

To patch and protect against the OpenSSL vulnerabilities CVE-2015-0291 and CVE-2015-0204, which were disclosed in March 2015, you can follow these steps:

1. Upgrade to the latest version of OpenSSL. The vulnerabilities were fixed in OpenSSL versions 1.0.1m and above. You can check the version of OpenSSL installed on your system by running the openssl version command.

To upgrade to the latest version of OpenSSL, you can follow the instructions for your operating system or distribution. For example, on a Debian-based system, you can use the apt-get command to update OpenSSL:

sudo apt-get update
sudo apt-get install openssl

2. Restart any services that use OpenSSL. After upgrading OpenSSL, you should restart any services that use OpenSSL to ensure that they are using the updated version.

For example, if you are using Apache with mod_ssl, you can restart Apache using the following command:

sudo service apache2 restart

3. Use strong passwords and enable two-factor authentication. To further protect against potential attacks, you should use strong passwords and enable two-factor authentication for any services that use OpenSSL. This can help prevent attackers from gaining access to your system even if they are able to exploit the vulnerabilities.
