The Red Hat Security Response Team has rated this update as having
critical security impact. Common Vulnerability Scoring System (CVSS)
base scores, which give detailed severity ratings, are available for
each vulnerability from the CVE links in the References section.

Adobe Reader allows users to view and print documents in Portable
Document Format (PDF).

This update fixes multiple security flaws in Adobe Reader. These flaws
are detailed on the Adobe security page APSB12-08, 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-2012-0774, CVE-2012-0775,
CVE-2012-0777)

All Adobe Reader users should install these updated packages. They
contain Adobe Reader version 9.5.1, which is not vulnerable to these
issues. All running instances of Adobe Reader must be restarted for
the update to take effect."
