Description:   Two vulnerabilities were reported in Adobe Flash Player. A remote user can cause arbitrary code to be executed on the target user's system.

A remote user can create a specially crafted SWF file that, when loaded by the target user, will trigger an input validation flaw and execute arbitrary code on the target system [CVE-2007-3456]. The code will run with the privileges of the target user.

A remote user can send a specially crafted HTTP Referer value to conduct cross-site request forgery attacks [CVE-2007-3457]. Flash Player 9 is not affected.

Adobe credits Stefano DiPaola, Elia Florio, and Giorgio Fedon with reporting the input validation vulnerability and Daiki Fukumori of Secure Sky Technology, Inc. with reporting the HTTP Referer vulnerability.
Impact:   A remote user can create a file that, when loaded by the target user, will execute arbitrary code on the target user's system.

A remote user can conduct cross-site request forgery attacks.

3. Problem description:

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.
