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: APSB08-15 at http://www.adobe.com/support/security/bulletins/apsb08-15.html CVE-2008-0883 at 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.

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.
