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

An input validation flaw was found in the way Flash Player displayed
certain content. It may be possible to execute arbitrary code on a victim's
machine if the victim opens a malicious Adobe Flash file. (CVE-2007-3456)

Users of Adobe Flash Player should upgrade to this updated package, which
contains version 9.0.47.0. and is not vulnerable to this issue.

4. Solution:

Before applying this update, make sure all previously released errata
relevant to your system have been applied.

To update all RPMs for your particular architecture, run:

rpm -Fvh [filenames]

where [filenames] is a list of the RPMs you wish to upgrade.  Only those
RPMs which are currently installed will be updated.  Those RPMs which are
not installed but included in the list will not be updated.  Note that you
can also use wildcards (*.rpm) if your current directory *only* contains the
desired RPMs.

Please note that this update is also available via Red Hat Network.  Many
people find this an easier way to apply updates.  To use Red Hat Network,
launch the Red Hat Update Agent with the following command:

up2date

This will start an interactive process that will result in the appropriate
RPMs being upgraded on your system.
