Synopsis |
| 16 |
======== |
| 17 |
|
| 18 |
Multiple vulnerabilities have been identified, the worst of which allow |
| 19 |
arbitrary code execution on a user's system via a malicious Flash file. |
| 20 |
|
| 21 |
Background |
| 22 |
========== |
| 23 |
|
| 24 |
The Adobe Flash Player is a renderer for the popular SWF file format, |
| 25 |
which is commonly used to provide interactive websites, digital |
| 26 |
experiences and mobile content. |

Description |
| 37 |
=========== |
| 38 |
|
| 39 |
Multiple vulnerabilities have been discovered in Adobe Flash Player: |
| 40 |
|
| 41 |
* The access scope of SystemsetClipboard() allows ActionScript |
| 42 |
programs to execute the method without user interaction |
| 43 |
(CVE-2008-3873). |
| 44 |
|
| 45 |
* The access scope of FileReference.browse() and |
| 46 |
FileReference.download() allows ActionScript programs to execute the |
| 47 |
methods without user interaction (CVE-2008-4401). |
| 48 |
|
| 49 |
* The Settings Manager controls can be disguised as normal graphical |
| 50 |
elements. This so-called "clickjacking" vulnerability was disclosed |
| 51 |
by Robert Hansen of SecTheory, Jeremiah Grossman of WhiteHat |
| 52 |
Security, Eduardo Vela, Matthew Mastracci of DotSpots, and Liu Die Yu |
| 53 |
of TopsecTianRongXin (CVE-2008-4503). |
| 54 |
|
| 55 |
* Matthew Dempsky reported a null-pointer dereference flaw when |
| 56 |
loading two SWF files compiled with different Flash versions from the |
| 57 |
same URI (CVE-2008-4546). |
| 58 |
|
| 59 |
* Adan Barth (UC Berkely) and Collin Jackson (Stanford University) |
| 60 |
discovered a flaw occurring when interpreting HTTP response headers |
| 61 |
(CVE-2008-4818). |
| 62 |
|
| 63 |
* Nathan McFeters and Rob Carter of Ernst and Young's Advanced |
| 64 |
Security Center are credited for finding an unspecified vulnerability |
| 65 |
facilitating DNS rebinding attacks (CVE-2008-4819). |
| 66 |
|
| 67 |
* When used in a Mozilla browser, Adobe Flash Player does not |
| 68 |
properly interpret jar: URLs, according to a report by Gregory |
| 69 |
Fleischer of pseudo-flaw.net (CVE-2008-4821). |
| 70 |
|
| 71 |
* Alex "kuza55" K. reported that Adobe Flash Player does not properly |
| 72 |
interpret policy files (CVE-2008-4822). |
| 73 |
|
| 74 |
* The vendor credits Stefano Di Paola of Minded Security for |
| 75 |
reporting that an ActionScript attribute is not interpreted properly |
| 76 |
(CVE-2008-4823). |
| 77 |
|
| 78 |
* Riley Hassell and Josh Zelonis of iSEC Partners reported multiple |
| 79 |
input validation errors (CVE-2008-4824). |
| 80 |
|
| 81 |
* The aforementioned researchers also reported that ActionScript 2 |
| 82 |
does not verify a member element's size when performing several known |
| 83 |
and other unspecified actions, that DefineConstantPool accepts an |
| 84 |
untrusted input value for a "constant count" and that character |
| 85 |
elements are not validated when retrieved from a data structure, |
| 86 |
possibly resulting in a null-pointer dereference (CVE-2008-5361, |
| 87 |
CVE-2008-5362, CVE-2008-5363). |
| 88 |
|
| 89 |
* The vendor reported an unspecified arbitrary code execution |
| 90 |
vulnerability (CVE-2008-5499). |
| 91 |
|
| 92 |
* Liu Die Yu of TopsecTianRongXin reported an unspecified flaw in the |
| 93 |
Settings Manager related to "clickjacking" (CVE-2009-0114). |
| 94 |
|
| 95 |
* The vendor credits Roee Hay from IBM Rational Application Security |
| 96 |
for reporting an input validation error when processing SWF files |
| 97 |
(CVE-2009-0519). |
| 98 |
|
| 99 |
* Javier Vicente Vallejo reported via the iDefense VCP that Adobe |
| 100 |
Flash does not remove object references properly, leading to a freed |
| 101 |
memory dereference (CVE-2009-0520). |
| 102 |
|
| 103 |
* Josh Bressers of Red Hat and Tavis Ormandy of the Google Security |
| 104 |
Team reported an untrusted search path vulnerability (CVE-2009-0521). |
| 105 |
|
| 106 |
Impact |
| 107 |
====== |
| 108 |
|
| 109 |
A remote attacker could entice a user to open a specially crafted SWF |
| 110 |
file, possibly resulting in the execution of arbitrary code with the |
| 111 |
privileges of the user or a Denial of Service (crash). Furthermore a |
| 112 |
remote attacker could gain access to sensitive information, disclose |
| 113 |
memory contents by enticing a user to open a specially crafted PDF file |
| 114 |
inside a Flash application, modify the victim's clipboard or render it |
| 115 |
temporarily unusable, persuade a user into uploading or downloading |
| 116 |
files, bypass security restrictions with the assistance of the user to |
| 117 |
gain access to camera and microphone, conduct Cross-Site Scripting and |
| 118 |
HTTP Header Splitting attacks, bypass the "non-root domain policy" of |
| 119 |
Flash, and gain escalated privileges. |
| 120 |
|
| 121 |
Workaround |
| 122 |
========== |
| 123 |
|
| 124 |
There is no known workaround at this time. |
| 125 |
|
| 126 |
Resolution |
| 127 |
========== |
| 128 |
|
| 129 |
All Adobe Flash Player users should upgrade to the latest version: |
| 130 |
|
| 131 |
# emerge --sync |
| 132 |
# emerge --ask --oneshot --verbose ">=net-www/netscape-flash-10.0.22.87" |
| 133 |
