   Reader may lead to Execution of Arbitrary Code and Overwrite Arbitrary
   Files          
   Bug ID: 6718894

   Product
   Solaris 10 Operating System

   Date of Workaround Release: 01-Aug-2008

   Date of Resolved Release: 10-Sep-2008

   SA Document Body
   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:

   http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2008-0883
   CVE-2008-2641 at
   http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2008-2641

   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

   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.

   disabled in the browser application.
