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

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 or create a Denial of Service (DoS) condition. In addition, Adobe Reader may give local users the ability to overwrite arbitrary files through the use of symbolic links.

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 121104-05

       
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 7.0.9 and versions 8.0 through 8.1.2 are affected by these issues.
   

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

$ /usr/bin/acroread -version
7.0.1

To determine earlier versions of Adobe Reader installed on a system, (ie. Solaris 10 3/05) the following command can be run (depending on whichever of the following files exists):

$ cat /usr/sfw/lib/Acrobat5/Reader/AcroVersion
5.0.10

$ cat /usr/lib/AdobeReader/Reader/AcroVersion

$ cat /usr/lib/AdobeReader/Adobe/Reader8/Reader/AcroVersion

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 avoid the issue described in CVE-2008-2641, 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

This issue is addressed in the following release:

SPARC Platform

• Solaris 10 with patch 121104-05 or later
