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: APSB08-13 at http://www.adobe.com/support/security/bulletins/apsb08-13.html CVE-2008-0667 at http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2008-0667 CVE-2007-5666 at http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2007-5666 CVE-2007-5659 at http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2007-5659 CVE-2007-5663 at http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2007-5663 CVE-2008-0726 at http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2008-0726 CVE-2008-0655 at http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2008-0655 CVE-2008-2042 at http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2008-2042 CVE-2007-4768 at http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2007-4768 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.

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.
