=====================================================================

 

1. Summary:

 

An updated Adobe Flash Player package that fixes several security issues is

now available for Red Hat Enterprise Linux 5 Supplementary.

 

This update has been rated as having important security impact by the Red

Hat Security Response Team.

 

2. Relevant releases/architectures:

 

RHEL Desktop Supplementary (v. 5 client) - i386, x86_64

RHEL Supplementary (v. 5 server) - i386, x86_64

 

3. Description:

 

The flash-plugin package contains a Firefox-compatible Adobe Flash Player

Web browser plug-in.

 

A flaw was found in the way Adobe Flash Player wrote content to the

clipboard. A malicious SWF file could populate the clipboard with a URL

that could cause the user to mistakenly load an attacker-controlled URL.

(CVE-2008-3873)

 

A flaw was found which allowed Adobe Flash Player's ActionScript to

initiate file uploads and downloads without user interaction.

FileReference.browse and FileReference.download calls can now only be

initiated via user interaction, such as mouse-clicks or key-presses on the

keyboard. (CVE-2008-4401)

 

A flaw was found in Adobe Flash Player's display of the Settings Manager

content. A malicious SWF file could trick the user into unknowingly

clicking a link or dialog. This could then give the malicious SWF file

permission to access the local machine's camera or microphone.

(CVE-2008-4503)

 

Flaws were found in the way Flash Player restricted the interpretation and

usage of cross-domain policy files. A remote attacker could use Flash

Player to conduct cross-domain and cross-site scripting attacks

(CVE-2007-4324, CVE-2007-6243). This update provides enhanced fixes for

these issues.

 

Adobe Flash Player 10 also includes bug fixes and feature enhancements

including:

 

* improved stability on the Linux platform by fixing a race condition issue

in sound output.

 

* new support for custom filters and effects, native 3D transformation and

animation, advanced audio processing, a new, more flexible text engine, and

GPU hardware acceleration.

 

For more information on new features and enhancements, see the Adobe Flash

Player site and the Adobe Labs Release Notes.

 

Note: some users may have installed a 3rd-party component, libflashsupport,

for older versions of Flash Player. Adobe Flash Player 10 no longer

supports libflashsupport. Users are advised to remove libflashsupport if

they have it installed.

 

All users of Adobe Flash Player should upgrade to this updated package,

which contains Flash Player version 10.0.12.36.
