Synopsis

========

 

Multiple vulnerabilities have been identified, the worst of which allow

arbitrary code execution on a user's system via a malicious Flash file.

 

Background

==========

 

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.

 

Affected packages

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

 

-------------------------------------------------------------------

Package / Vulnerable / Unaffected

-------------------------------------------------------------------

1 net-www/netscape-flash < 10.0.22.87 >= 10.0.22.87

 

Description

===========

 

Multiple vulnerabilities have been discovered in Adobe Flash Player:

 

* The access scope of SystemsetClipboard() allows ActionScript

programs to execute the method without user interaction

(CVE-2008-3873).

 

* The access scope of FileReference.browse() and

FileReference.download() allows ActionScript programs to execute the

methods without user interaction (CVE-2008-4401).

 

* 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).

 

* Matthew Dempsky reported a null-pointer dereference flaw when

loading two SWF files compiled with different Flash versions from the

same URI (CVE-2008-4546).

 

* Adan Barth (UC Berkely) and Collin Jackson (Stanford University)

discovered a flaw occurring when interpreting HTTP response headers

(CVE-2008-4818).

 

* 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).

 

* 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).

 

* Alex "kuza55" K. reported that Adobe Flash Player does not properly

interpret policy files (CVE-2008-4822).

 

* The vendor credits Stefano Di Paola of Minded Security for

reporting that an ActionScript attribute is not interpreted properly

(CVE-2008-4823).

 

* Riley Hassell and Josh Zelonis of iSEC Partners reported multiple

input validation errors (CVE-2008-4824).

 

* 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).

 

* The vendor reported an unspecified arbitrary code execution

vulnerability (CVE-2008-5499).

 

* Liu Die Yu of TopsecTianRongXin reported an unspecified flaw in the

Settings Manager related to "clickjacking" (CVE-2009-0114).

 

* The vendor credits Roee Hay from IBM Rational Application Security

for reporting an input validation error when processing SWF files

(CVE-2009-0519).

 

* 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).

 

* Josh Bressers of Red Hat and Tavis Ormandy of the Google Security

Team reported an untrusted search path vulnerability (CVE-2009-0521).

 

Impact

======

 

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

==========

 

There is no known workaround at this time.

 

Resolution

==========

 

All Adobe Flash Player users should upgrade to the latest version:

 

# emerge --sync

# emerge --ask --oneshot --verbose ">=net-www/netscape-flash-10.0.22.87"
