Adobe Acrobat / Adobe Reader Disclosure of Sensitive Information

Moderately critical

Exposure of sensitive information

From remote

Adobe Reader 6.x
Adobe Acrobat 6.x

Jelmer has discovered a vulnerability in Adobe Acrobat and Adobe
Reader, which can be exploited by malicious people to disclose
sensitive information.

The problem is that embedded Macromedia flash files are executed in a
local context. This can be exploited to read local files by embedding
a specially crafted flash file in a PDF file located on e.g. a
malicious web site.

The vulnerability has been confirmed on Adobe Reader 6.01 and 6.02
for Windows.

Disable Javascript in Adobe Acrobat and Adobe Reader.

I know I do have Adobe Acrobat as I sometimes read something in that format. Where the heck do you find it? I looked in my plug ins and it wasn't listed there. Also, I have no idea what version I would have.

How do we go about disabling Javascript in Adobe Acrobat?

Hi Pat,

look under Program Files > Adobe > Reader.

Open Adobe Reader > Edit > Preferences > Java Script - there you can disable it by taking out the checkmark "enable".

The version I have is 6.0.2. - seems to be the latest Wink
