After reading about Poodle secutrity bug, I have disabled SSLv3 on my servers and browsers.

But there are several clients that do not expose settings detailed enough via their own means of configuration, e.g. owncloud, uzbl-browser. Also, come to think about it, it is kind of cumbersome to go through every single client...

Apart from rebuilding SSL libraries they use, is there way how to set up a system-wide default or a policy for simplistic (or "irresponsible", if you want) clients like that?

I was kind of expecting to find something in /etc/ssl but that only seems to address certificates and autorities.

    The simple answer is no, unfortunately this is not possible.

    Because Poodle relies on adaptive chosen plaintext, it's really only web browsers that are vulnerable, which should reduce your workload a little

  • @paj28 That's not accurate, not just browsers go through HTTPS (HTTP API's, for example).

    @Robert - Only browsers are vulnerable to Poodle. See this answer for more information.

Its possible to make changes to the TCP/IP SSL levels, but not really considered a policy per say, You might be able to use a deployment service to make the changes using AutoIT (I make company wide changes with this as my deployment asset.


If you implement SSL-proxying, you can configure your proxy server (e.g. Squid) to not use SSLv3 to any side of the connection (client-to-proxy and proxy-to-web).
