A critical vulnerability has been identified in Adobe Reader 9 and Acrobat 9 (for both Mac and PC platforms) and earlier versions. This vulnerability would cause the application to crash and could potentially allow an attacker to take control of the affected system. There are reports that this issue is being exploited.
Adobe is planning to release updates to Adobe Reader and Acrobat to resolve the relevant security issue. Adobe expects to make available an update for Adobe Reader 9 and Acrobat 9 by March 11th, 2009. Adobe is planning to make updates for Adobe Reader 7 and 8, and Acrobat 7 and 8, available by March 18th. In the meantime, Adobe is in contact with anti-virus and security vendors, including McAfee, Symantec and others, on this issue in order to ensure the security of our mutual customers. More information on protection for this issue from anti-virus and security vendors is now available on the Adobe Product Security Incident Response Team blog.
Reports have been published that disabling JavaScript in Adobe Reader and Acrobat can protect users from this issue. Disabling JavaScript provides protection against currently known attacks. However, the vulnerability is not in the scripting engine and, therefore, disabling JavaScript does not eliminate all risk. Should users choose to disable JavaScript, it can be accomplished following the instructions below:
1. Launch Acrobat or Adobe Reader.
2. Select Edit>Preferences
3. Select the JavaScript Category
4. Uncheck the ‘Enable Acrobat JavaScript’ option
5. Click OK
A security bulletin will be published on http://www.adobe.com/support/security as soon as product updates are available.
