Synopsis

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

Description

The remote Redhat Enterprise Linux 6 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2011:1434 advisory.

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.

Tenable has extracted the preceding description block directly from the Red Hat Enterprise Linux security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.
