Alert: Adobe Acrobat/Reader Upgrade Email Spam/Phishing Scam

With the availability of Adobe Acrobat X solutions this week, a reminder to be cautious when receiving email messages purporting to offer a download of a new version of Adobe Acrobat or Adobe Reader sent by entities claiming to be Adobe.

Many of these emails require recipients to register and/or provide personal information. Please be aware that these emails have not been sent by Adobe or on Adobe’s behalf.

The Adobe Reader, in particular, is free software available for download directly from the Adobe Reader download page on the Adobe website at http://get.adobe.com/reader/; it is not available in any other manner via download, including via email.

Customers receiving one of these potentially malicious emails should delete the email immediately without clicking on any of the links.

Potential issue in Adobe Reader

Adobe is aware of a potential issue in Adobe Reader posted publicly today on the Full Disclosure list. A proof-of-concept file demonstrating a Denial of Service was published. Arbitrary code execution has not been demonstrated, but may be possible. We are currently investigating this issue. In the meantime, users of Adobe Reader 9.2 or later and 8.1.7 or later can utilize the JavaScript Blacklist Framework to prevent the issue by following the instructions below. Note that Adobe Acrobat is not affected by this issue.


Adobe Reader 9.2 and later and Adobe Reader 8.1.7 and later – Windows

On Windows, the JavaScript Blacklist can be in two locations. Please review the following options and then create the registry key of your choice:

Enterprise list: This blacklist helps enterprises roll out policies that block exploitable API(s) from executing in their environment. Populating the blacklist in this location is the responsibility of the enterprise. Adobe patches never modify this registry location.
To create the registry key:
HKLM\SOFTWARE\Policies\Adobe\<product>\<version>\FeatureLockDown\cJavaScriptPerms\tBlackList

Adobe’s update/patch list: The Adobe blacklist is modified by Adobe Reader patches whenever an API is deemed vulnerable. APIs are also removed from the blacklist whenever a fix for a vulnerability is provided by the current patch.
To create the registry key:
HKLM\SOFTWARE\Adobe\<product>\<version>\JavaScriptPerms\tBlackList

    On a 64 bit Windows system, the path is:
    HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Adobe

->To prevent this particular issue, add the following value to the registry key created in the previous step (case sensitive):
Doc.printSeps

->Exit and restart the application
