<p>
The Adobe Flash Player is a renderer for the popular SWF file format,
which is commonly used to provide interactive websites, digital
experiences and mobile content.

<description>
<p>
Multiple vulnerabilities have been discovered in Adobe Flash Player:
</p>
<ul>
<li>The access scope of SystemsetClipboard() allows ActionScript
programs to execute the method without user interaction
(CVE-2008-3873).</li>
<li>The access scope of FileReference.browse() and
FileReference.download() allows ActionScript programs to execute the
methods without user interaction (CVE-2008-4401).</li>
<li>The Settings Manager controls can be disguised as normal graphical
elements. This so-called "clickjacking" vulnerability was disclosed by
Robert Hansen of SecTheory, Jeremiah Grossman of WhiteHat Security,
Eduardo Vela, Matthew Mastracci of DotSpots, and Liu Die Yu of
TopsecTianRongXin (CVE-2008-4503).</li>
<li>Adan Barth (UC Berkely) and Collin Jackson (Stanford University)
discovered a flaw occurring when interpreting HTTP response headers
(CVE-2008-4818).</li>
<li>Nathan McFeters and Rob Carter of Ernst and Young's Advanced
Security Center are credited for finding an unspecified vulnerability
facilitating DNS rebinding attacks (CVE-2008-4819).</li>
<li>When used in a Mozilla browser, Adobe Flash Player does not
properly interpret jar: URLs, according to a report by Gregory
Fleischer of pseudo-flaw.net (CVE-2008-4821).</li>
<li>Alex "kuza55" K. reported that Adobe Flash Player does not properly
interpret policy files (CVE-2008-4822).</li>
<li>The vendor credits Stefano Di Paola of Minded Security for
reporting that an ActionScript attribute is not interpreted properly
(CVE-2008-4823).</li>
<li>Riley Hassell and Josh Zelonis of iSEC Partners reported multiple
input validation errors (CVE-2008-4824).</li>
<li>The aforementioned researchers also reported that ActionScript 2
does not verify a member element's size when performing several known
and other unspecified actions, that DefineConstantPool accepts an
untrusted input value for a "constant count" and that character
elements are not validated when retrieved from a data structure,
possibly resulting in a null-pointer dereference (CVE-2008-5361,
CVE-2008-5362, CVE-2008-5363).</li>
<li>The vendor reported an unspecified arbitrary code execution
vulnerability (CVE-2008-5499).</li>
<li>Liu Die Yu of TopsecTianRongXin reported an unspecified flaw in the
Settings Manager related to "clickjacking" (CVE-2009-0114).</li>
<li>The vendor credits Roee Hay from IBM Rational Application Security
for reporting an input validation error when processing SWF files
(CVE-2009-0519).</li>
<li>Javier Vicente Vallejo reported via the iDefense VCP that Adobe
Flash does not remove object references properly, leading to a freed
memory dereference (CVE-2009-0520).</li>
<li>Josh Bressers of Red Hat and Tavis Ormandy of the Google Security
Team reported an untrusted search path vulnerability
(CVE-2009-0521).</li>
</ul>
</description>
<impact type="normal">
<p>
A remote attacker could entice a user to open a specially crafted SWF
file, possibly resulting in the execution of arbitrary code with the
privileges of the user or a Denial of Service (crash). Furthermore a
remote attacker could gain access to sensitive information, disclose
memory contents by enticing a user to open a specially crafted PDF file
inside a Flash application, modify the victim's clipboard or render it
temporarily unusable, persuade a user into uploading or downloading
files, bypass security restrictions with the assistance of the user to
gain access to camera and microphone, conduct Cross-Site Scripting and
HTTP Header Splitting attacks, bypass the "non-root domain policy" of
Flash, and gain escalated privileges.
</p>
</impact>
<workaround>
<p>
There is no known workaround at this time.
</p>
</workaround>
<resolution>
<p>
All Adobe Flash Player users should upgrade to the latest version:
</p>
<code>
# emerge --sync
# emerge --ask --oneshot --verbose ">=www-plugins/adobe-flash-10.0.22.87"</code>
</resolution>
