This update fixes two security flaws in Adobe Reader. These flaws are

opened. (CVE-2011-2462, CVE-2011-4369)

All Adobe Reader users should install these updated packages. They contain
Adobe Reader version 9.4.7, which is not vulnerable to these issues. All
running instances of Adobe Reader must be restarted for the update to take
