To contribute back, here is my .reg file that I'm applying in the login script:
Windows Registry Editor Version 5.00
and here is the email that I'm sending to all users to suggest they secure their home computers:
Adobe have announced that there is currently a serious security vulnerability in Adobe Acrobat Reader. IT have already applied their recommended settings here at work so you do not need to do anything here.
If you want to know more, read on.
If you would like more details of this, or to confirm this, then Adobe's own security advisory is online at http://www.adobe.com/support/security/advisories/apsa09-07.html
IT always recommend that you should confirm any security alert you receive yourself with the official website of the company that has the problem, or with trustworthy official sources such as the US Government's CERT (www.cert.org - CERT's warning about this vulnerability is at http://www.kb.cert.org/vuls/id/508357). There are lots of fake security alerts that are intended either to "cry wolf" so people ignore real ones like this, or to induce you to buy software you don't need, or to download and install software that is harmful to your computer, so you should always check the alert yourself.
