The remote host is missing updates announced in
advisory RHSA-2008:0980.
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 (Shockwave Flash) file could populate the
clipboard with a URL that could cause the user to accidentally or
mistakenly load an attacker-controlled URL. (CVE-2008-3873)
A flaw was found with Adobe's ActionScript scripting language which allowed
Flash scripts to initiate file uploads and downloads without user
interaction. ActionScript's FileReference.browse and FileReference.download
method calls can now only be initiated via user interaction, such as
through mouse-clicks or key-presses on the keyboard. (CVE-2008-4401)
A flaw was found in Adobe Flash Player's display of Settings Manager
content. A malicious SWF file could trick the user into unintentionally or
mistakenly clicking a link or a dialog which 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.
Flash Player contains a flaw in the way it interprets HTTP response
headers. An attacker could use this flaw to conduct a cross-site scripting
attack against the user running Flash Player. (CVE-2008-4818)
A flaw was found in the way Flash Player handles the ActionScript
attribute. A malicious site could use this flaw to inject arbitrary HTML
content, confusing the user running the browser. (CVE-2008-4823)
A flaw was found in the way Flash Player interprets policy files. It was
possible to bypass a non-root domain policy, possibly allowing a malicious
site to access data in a different domain. (CVE-2008-4822)
A flaw was found in how Flash Player's jar: protocol handler interacts with
Mozilla. A malicious flash application could use this flaw to disclose
sensitive information. (CVE-2008-4821)
Updated Flash Player also extends mechanisms to help prevent an attacker
from executing a DNS rebinding attack. (CVE-2008-4819)
All users of Adobe Flash Player should upgrade to this updated package,
which contains Flash Player version 9.0.151.0.
