Topic

An updated Adobe Flash Player package that fixes several security issues is
now available for 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.

Description

The flash-plugin package contains a Mozilla Firefox compatible Adobe Flash
Player web browser plug-in.

This update fixes several vulnerabilities in Adobe Flash Player. These
vulnerabilities are detailed on the Adobe security page APSB12-14, listed
in the References section.

Several security flaws were found in the way flash-plugin displayed certain
SWF content. An attacker could use these flaws to create a
specially-crafted SWF file that would cause flash-plugin to crash or,
potentially, execute arbitrary code when the victim loaded a page
containing the specially-crafted SWF content. (CVE-2012-2034,
CVE-2012-2035, CVE-2012-2036, CVE-2012-2037, CVE-2012-2039)

A flaw in flash-plugin could allow an attacker to obtain sensitive
information if a victim were tricked into visiting a specially-crafted web
page. (CVE-2012-2038)

All users of Adobe Flash Player should install this updated package, which
upgrades Flash Player to version 10.3.183.20.
