Multiple Security Vulnerabilities in the Adobe Reader may lead to Execution of Arbitrary Code

1. Impact

Multiple security vulnerabilities in the Adobe Reader may allow remote unprivileged users to execute arbitrary code with the permissions of the local user.  These vulnerabilities may include validation check errors within the Adobe Reader's JavaScript handling, a heap-based buffer overflow in the Perl-Compatible Regular Expression (PCRE) library, and an untrusted search path error.

Adobe Reader is the free viewing companion to Adobe Acrobat.  Adobe Reader allows you to view, navigate, and print Portable Document Format (PDF) files.

These issues are described in the following documents:


2. Contributing Factors

These issues can occur in the following release:

SPARC Platform

• Solaris 10 without patch 121136-02 (Adobe Reader Plugin) and patch 121104-03 (Adobe Reader)

   
Notes:

1. Solaris 8, Solaris 9, Solaris 10 on the x86 platform and OpenSolaris do not ship Adobe Reader and therefore are not affected by this issue.
2. All versions of Adobe Reader and Acrobat up to and including version 7.0.8 are affected by these issues. Solaris 10 ships Acrobat Reader 7.0.
   

To determine the version of Adobe Reader installed on a system, the following command can be run:

$ /usr/bin/acroread -version
7.0.1

3. Symptoms

There are no predictable symptoms that would indicate these issues have been exploited to execute arbitrary code.

4. Workaround

To avoid the described issues, do not load PDF files from untrusted sources.

To work around the issues described in CVE-2008-0667, CVE-2007-5659, CVE-2007-5663, and CVE-2008-2042, JavaScript can be disabled in the browser application. 

This can done in Mozilla as follows:

1. Open the 'Preferences' dialog from the Edit menu
2. Select the 'Advanced' tree
3. Select the 'Scripts & Plug-ins' leaf
4. Uncheck the 'Navigator' check box
5. Click the OK button
   

This can be done in Firefox as follows:

1. Open the 'Preferences' dialog from the Edit menu
2. Select the 'Content' tab
3. Uncheck the 'Enable JavaScript' check box
4. Click the Close button
   

5. Resolution

These issues are addressed in the following release:

SPARC Platform

• Solaris 10 with patch 121136-02 (Adobe Reader Plugin) and patch 121104-03 (Adobe Reader)
