3. Description:
Adobe Reader allows users to view and print documents in Portable Document
Format (PDF).
This update fixes two security flaws in Adobe Reader. These flaws are
detailed on the Adobe security page APSB11-30, listed in the References
section. A specially-crafted PDF file could cause Adobe Reader to crash or,
potentially, execute arbitrary code as the user running Adobe Reader when
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
effect.
