This script is Copyright (C) 2011-2014 Tenable Network Security, Inc.


Synopsis :

The remote Red Hat host is missing one or more security updates.

Description :

Updated acroread packages that fix multiple security issues are now
available for Red Hat Enterprise Linux 4 Extras and Red Hat Enterprise
Linux 5 and 6 Supplementary.

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 APSB11-24, 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-2011-2431, CVE-2011-2432,
CVE-2011-2433, CVE-2011-2434, CVE-2011-2435, CVE-2011-2436,
CVE-2011-2437, CVE-2011-2438, CVE-2011-2439, CVE-2011-2440,
CVE-2011-2442)

This update also fixes multiple security flaws in Adobe Flash Player
embedded in Adobe Reader. These flaws are detailed on the Adobe
security pages APSB11-21 and APSB11-26, listed in the References
section.

A PDF file with an embedded, specially-crafted SWF file could cause
Adobe Reader to crash or, potentially, execute arbitrary code as the
user running Adobe Reader when opened. (CVE-2011-2130, CVE-2011-2134,
CVE-2011-2135, CVE-2011-2136, CVE-2011-2137, CVE-2011-2138,
CVE-2011-2139, CVE-2011-2140, CVE-2011-2414, CVE-2011-2415,
CVE-2011-2416, CVE-2011-2417, CVE-2011-2424, CVE-2011-2425,
CVE-2011-2426, CVE-2011-2427, CVE-2011-2428, CVE-2011-2430)

A flaw in Adobe Flash Player could allow an attacker to conduct
cross-site scripting (XSS) attacks if a victim were tricked into
visiting a specially-crafted web page. (CVE-2011-2444)

This update also fixes an information disclosure flaw in Adobe Flash
Player. (CVE-2011-2429)

All Adobe Reader users should install these updated packages. They
contain Adobe Reader version 9.4.6, which is not vulnerable to these
issues. All running instances of Adobe Reader must be restarted for
the update to take effect.
