Hello everyone,

On behalf of the Plone Foundation I'd like to draw your attention to a security announcement that was published about 12 hours ago.

This is a pre-announcement only, it does not contain any vulnerability details. Your sites are a safe today as they were yesterday.  However, as the problem that has been found is so serious we are giving you advance warning that a patch is upcoming and recommending that you plan a maintenance period for your sites to coincide with the full announcement next week.

Full details are available athttp://plone.org/products/plone/security/advisories/cve-2011-0720

You can feel free to ask more questions on the plone-users mailing list or in the #plone IRC channel about details and how to protect yourself, but it is important to make a plan for this now.  If you know you can't have a planned down-time at the time specified in that announcement you should plan to implement one of the workarounds before next tuesday, otherwise your site is potentially at risk.

I'd like to thank everyone that's been involved in finding, isolating and fixing this problem, especially Alan Hoey of Team Rubber for his responsible disclosure of the bug to the security team.  

Matthew
