"An updated Adobe Flash Player package that fixes three 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.

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

This update fixes multiple vulnerabilities in Adobe Flash Player.
These vulnerabilities are detailed in the Adobe Security Bulletin
APSB14-17, listed in the References section.

Multiple 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 malicious SWF content. (CVE-2014-0537, CVE-2014-0539)

This update also fixes a flaw that would lead to Cross-Site Request
Forgery (CSRF) attacks. (CVE-2014-4671)

All users of Adobe Flash Player should install this updated package,
which upgrades Flash Player to version 11.2.202.394."
