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 or create a Denial of Service (DoS) condition.

In addition, Adobe Reader, when used as a browser plugin, may give remote users the ability to execute arbitrary code within the browser with the permissions of the local user.

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 121104-06

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-2008-2992 and CVE-2008-4814, JavaScript can be disabled in the browser application.

This can done in Mozilla as follows:


This can be done in Firefox as follows:


5. Resolution

These issues are addressed in the following release:

SPARC Platform

• Solaris 10 with patch 121104-06 or later
