Magento will officially be making the patch available tomorrow, Tuesday, October 27th.  We have tested the previous patch on several development websites and will be installing this new patch on several others.  We'll update you when we know more.

Below is the official security announcement from Magento.

A point of clarification - Modern Retail is installing and testing this patch now on three different websites in our test environment.  This is being done to see how the current patch affects the extensions that are installed on these sites.  Depending on the outcome of our testing, we may apply the patch to our production websites.

We received a copy of the updated patch and have installed it in our test environment.  Unfortunately, the update is breaking a lot of 3rd party extensions.  We're testing the most frequently used extensions now and may even have to create separate instances of certain client websites to vet any possible problems or issues.

More information will be posted here as we know more, and we'll be contacting each Magento customer separately regarding the status of this patch.  Thank you.

Tonight we received the following notice from Magento regarding two security updates:

We have two security updates to share with you today: information about a malware issue impacting some Magento sites and an unrelated security patch release planned for Wednesday, October 21, 2015.

Magento has asked us not to share any other information with you until the patches are officially released tomorrow.  Please hang tight, more information coming soon.
