Don’t let DROWN get you down

drown-blogpost.jpg

If you’re maintaining services on the internet, you know about the importance of keeping up to date with security patches as they come available. Today is no exception with the release of  CVE-2016-0800, describing the ‘DROWN’ vulnerability in OpenSSL.

The key points of DROWN are that it can allow for passive decryption of encrypted traffic, via vulnerabilities in the obsolete SSLv2 protocol. Merely using SSLv2 for one service could cause the compromise the traffic of other services, even if they aren’t using SSLv2. More information can be found at http://www.drownattack.com/.

The Red Hat specific announcement can be found in the  Red Hat Knowledgebase.

Obviously, this is a big deal, but patching your systems for DROWN doesn’t have to be a big deal, thanks to Ansible.

Here’s a sample playbook for Red Hat/Fedora/CentOS and Debian/Ubuntu systems (link to source):

- hosts: all
  gather_facts: true
  sudo: true
  tasks:
	- name: update openssl from apt if available
  	  apt: name=openssl state=latest update_cache=yes
  	  when: ansible_os_family == 'Debian'
  	  notify: restart_system
  
	- name: update openssl from yum if available
  	  yum: name=openssl state=latest update_cache=yes
  	  when: ansible_os_family == 'RedHat'
  	  notify: restart_system
