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.

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>

<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.
|

<workaround>
|
|
<p>
|
|
There is no known workaround at this time.

</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>
