Synopsis :

The remote Red Hat host is missing a security update.

Description :

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 critical security impact by the
Red Hat Security Response Team.

[Updated 18th November 2008] The erratum has been updated to include
references to the additional CVE-named issues that were not public at
the time of release. The security impact of the erratum has also been
upgraded to Critical. No changes have been made to the packages.

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.
