Red Hat Product Security has rated this update as having a security

score, which gives a detailed severity rating, is available for each
vulnerability from the CVE link(s) in the References section.

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

This update upgrades Flash Player to version 24.0.0.221.

Security Fix(es) :

* This update fixes multiple vulnerabilities in Adobe Flash Player.
These vulnerabilities, detailed in the Adobe Security Bulletin listed
in the References section, could allow an attacker to create a
specially crafted SWF file that would cause flash-plugin to crash,
execute arbitrary code, or disclose sensitive information when the
victim loaded a page containing the malicious SWF content.
