Potential vulnerabilities in Adobe Reader and Acrobat

Release date: November 28, 2006

Vulnerability identifier: APSA06-02

CVE number: CVE-2006-6027

Platform: Windows

Summary

Adobe is aware of a recently published report of potential vulnerabilities in Adobe Reader and Acrobat. These vulnerabilities would cause the application to crash and could potentially allow an attacker to take control of the affected system.

Affected software versions

Adobe Reader 7.0.0 through 7.0.8 and Adobe Acrobat Standard and Professional 7.0.0 through 7.0.8 on the Windows platform when using Internet Explorer. Users of other browsers are not affected.

Solution

The Secure Software Engineering team is working with the Adobe Reader Engineering team on an update to Adobe Reader and Acrobat 7.0.8 that will resolve these issues, which is expected to be available in the near future.
A security bulletin will be published on http://www.adobe.com/support/security
as soon as that update is available.

The upcoming version of Adobe Reader, which will not be vulnerable to this issue, is also expected to be available in the near future. Acrobat 8 is not affected by this issue. The vulnerability is in an ActiveX control used by Internet Explorer; users of other browsers are not affected. The following workaround will prevent these vulnerabilities from occurring in Adobe Reader 7.0.X on Windows using Internet Explorer:

1. Exit Internet Explorer and Adobe Reader.
2. Browse to :\Program Files\Adobe\Acrobat 7.0\ActiveX.
Note: If you did not install Acrobat to the default location, browse to
the location of your Acrobat 7.0 folder.
3. Select AcroPDF.dll and delete it.

NOTE: This workaround will prevent PDF documents from opening within an Internet Explorer window. After applying this workaround, clicking on PDF files within Internet Explorer will either open in a separate instance of Adobe Reader or the user will be prompted to download the file, which can then be opened in Adobe Reader. This workaround may disrupt some enterprise workflows and use of PDF forms.

All documented security vulnerabilities and their solutions are distributed through the Adobe security notification service. You can sign up for the service at the following URL:

Severity rating

Adobe categorizes this as a critical issue.
