to take control of your computer. Adobe has released Security
Bulletin APSB09-07, which describes the issues.
Solution
Update
Adobe has released updates to address this issue. Users are
encouraged to read Adobe Security Bulletin APSB09-07 and update
vulnerable versions of Adobe Reader and Acrobat.
Disable JavaScript in Adobe Reader and Acrobat
Disabling Javascript may prevent some exploits from resulting in
code execution. Acrobat JavaScript can be disabled using the
Preferences menu:
* Open the Edit menu.
* Select Preferences.
* Choose JavaScript.
* Un-check Enable Acrobat JavaScript.
Disable the display of PDF documents in the web browser
Preventing PDF documents from opening inside a web browser will
partially mitigate this vulnerability. This workaround may also
mitigate future vulnerabilities.

browser, do the following:
* Open Adobe Acrobat Reader.
* Open the Edit menu.
* Choose the Preferences option.
* Choose the Internet section.
* Un-check the Display PDF in browser check box.
Do not access PDF documents from untrusted sources
Do not open unfamiliar or unexpected PDF documents, particularly
those hosted on websites or delivered as email attachments. See
